(Optional: Measure the rainfall and wind speed. Mindmaps can also be a useful way of summarizing information and studying, however, we are using concept maps as they help to show linkages, which is very important in science. Analyze MAPS to determine the impact of habitat destruction in the rainforest! Each of these levels in the food chain is called a trophic level. Here is a quick preview: Interspecies interactions can be broken into three main categories: competition, predation, and symbiosis. Some ecosystems are under strain and others have already collapsed. Organisms which cannot produce their own food need to eat other organisms to get food. When animals are poached, they are killed at a faster rate than their population can grow. You can help them come to the answers by asking leading questions, such as, how would the scientists compare the habitats of the two populations? Plants are producers because they make their own food during photosynthesis. Animals that eat primary consumers are called, Animals that eat the secondary consumers (mostly predators) are the. There are two labels missing, but lines have been provided for you to fill them in on the diagram. An ecosystem consists of a community that includes all living organisms (biotic) such as plants and animals, together with the non-living (abiotic) environment and climatic conditions such as temperature, air and wind, water, interacting as a system. Many years ago, people like the San had little impact on their environment, as they lived in harmony with the land and only took what food they could carry. Humans also poach endangered animals and over-harvest marine animals, causing lasting damage to ecosystems. The unique way that the organism survives within its environment. Scientists say they need to send new equipment to Mars, equipment Communication (from Latin: communicare, meaning "to share" or "to be in relation with") is "an apparent answer to the painful divisions between self and other, private and public, and inner thought and outer world." They obtain food from plants either directly (such as herbivores) or indirectly (such as carnivores). The balance can be disturbed by natural or human factors: natural factors include extreme changes in patterns of weather and climate, such as floods, drought, extreme and sudden changes in temperature. An insectivore eats insects and small invertebrates and is therefore a carnivore, as it eats other animals, thus the statement is correct because carnivores get their energy from eating other animals and not plants. There are fewer than 200 individuals left in South Africa. Look at the following photographs of different fungi. Includes LEARNING TARGETS, SUCCESS CRITERIA, Activities, and Review Questions for each lesson. Let's look at some of the animals that live in our country and how they have adapted to live in their environments. Biotic factors are those factors that have once lived or that are living today. See this link: http://www.rain-barrel-world.com/homemade-rain-gauge.html, Build your own wind meter. to personalise content to better meet the needs of our users. Rather, it is defined by the area that you are talking about and whether the individuals can interact. Identify the different populations of organisms that make up this underwater community which is part of the ocean. The organisms in each level use most of the energy (\(\text{90}\)%) to sustain their own life processes (such as breathing, moving, reproducing etc). Large geographic areas with similar climates and ecosystems. Start learning today with flashcards, games and expert-written solutions. That would be predation. Photosynthesis in plants uses carbon dioxide to produce glucose. *This bundle includes information on the following topics: - Living Earth - Populations - Interactions Within Communities - Abiotic Factors in Ecosystems - Cycles in Nature - Energy Flow - Ecosystems - Biomes - Aquatic Ecosystems - Resources - Pollution - Conservation These Life Science Self Studies (Guided Notes) can be used as efficient study These organisms are called consumers. The name 'Lithops' comes from two Ancient Greek words lithos meaning 'stone' and ops meaning 'face'. Body adapted to mimic leaf or stick; moves very slowly to seem like a branch or leaf moving; nocturnal to avoid being seen in daylight by predators; stick insects can reproduce without male insects, Structural: body structured to resemble leaf or stick, Behavioural: nocturnal as it feeds under cover of darkness; moves slowly to not attract predators. Why do you think the plants have such different patterns on their surfaces? Herbivores get energy directly from plants, but carnivores and omnivores eat animals for energy. Let's take a closer look at each. A video of leaf cutter ants tending to their fungi farm. They might have seen earthworms or fungi. What types of grasses do specific herbivores eat and what eats the herbivores? It has a strong tail, stream lined body and its forelimbs are flippers for swimming. It takes the combined work of many concerned people to maintain healthy ecosystems - you can also make a difference! An ecosystem can only accommodate as many organisms as its resources (food, water and shelter) can carry. Explain your answer. If the change occurs over long periods, like climate change and global warming, the damage may not be reversible. A possible enrichment activity, or homework task is to get learners to read the article, and then this webpage has questions that you can ask your learners in an informal discussion: http://www.sciencenewsforkids.org/teachers-questions-for-cool-jobs-green-science/. Year Level Read more about Data analysis worksheet - Turtle hatching rates. Describe the impact that this could have on the rest of the food chain or food web. [4 marks]. It is illegal to buy or sell Perlemoen! [2 marks]. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. Individuals live together in populations. How does this help the plant survive? Biotic Factors All of the living components. Keywords: biodiversity, captive breeding, conservation, ecosystem, endangered, environment, extirpated, habitat, habitat organisms and between organisms and their environment. A carnivore that eats mainly insects and other small invertebrates, Distinguish between abiotic and biotic factors in the environment. You can even draw some illustrations. We will be studying this in more detail next, but learners would have done this in previous grades. Living organisms need to feed to be able to perform the other life processes. Printable materials & digital, interactive versions of the resources are included. Extension question to ask your learners: Another group of scientists wants to compare the population of penguins at Boulders Beach in Cape Town with another population in Antarctica. In the overview, they made mention of herbivory. Ecology is the study of the interactions among organisms and their environments. Today we worked through some of the vocabulary for interactions with an ecosystem. Adaptation, over time, allows a species to survive in response to changing conditions in the environment, Species that are unable to adapt to changes within the environment die out (become extinct). The producers capture the energy from the sunlight and convert it to chemical potential energy in the form of glucose through the process of photosynthesis. Soil physical, chemical and biological properties and processes are all examined in detail through class lectures and . Another way in which humans have a huge impact on the environment and cause disruption to ecosystems is through pollution. The points in CAPS are a misconception and should be reworded as follows: Be sure to make it clear that it is species or populations of organisms that adapt, and not individual organisms. Competition Organisms of two species use the same limited resource and have a negative impact on each other. Body adapted to dig and reach into nests to get prey; little hair as lives in hot climate; has shovel-like claws and powerful short limbs, long sticky tongue to pick up and eat the ants. You can use illustrations. study of interactions that take place among organisms and their environment. But ecosystems cannot do this effectively if we interfere. Use the following space to write about your observations and draw images. This grassland ecosystem has a sloped surface. Cape gangsters have taken over the illegal Perlemoen trade because of the huge amounts of money involved. If teachers have taught learners to use basic light microscopes they should encourage them to study these with the use of a microscope too. Support companies that dispose of their waste responsibly. Find everything you need to teach with this ecology and ecosystems unit bundle that is complete with a guiding PowerPoint, tons of activities, graphic organizers and more, plus one of our favorite projects, the Biorama! How would removal of 95% of the stomach (subtotal gastrectomy) to treat severe ulcers or cancer affect digestion and absorption? Google Classroom versions of the resources are also available in my store: BUNDLE | Google Classroom | Human Environment Interactions |, This student workbook allows students to take notes and answer questions during the grade 7 ecology unit on ecosystems. Look at the following illustration which shows the levels of organisation. Just as the uranium series is called the " 4n+24 n+24n+2 " series, the thorium series can be called the " 4n4 \mathrm{n}4n " series, and the actinium series the " 4n+34 n+3^{\prime \prime}4n+3 series. Learners should take note of the water resources in their square, the slope of the land, and the type of soil and how this affects the organisms. A lion is an example of a predator. The sea anemone protects the clown fish from predators, the clown fish feeds on small invertebrates which might harm the anemone and the anemone also gets nutrients from the fish's fecal matter. Why does there seem to be such a large difference in numbers? http://revolution.caret.cam.ac.uk/flash/ecosystems_younger.swf. For example, stepping on an ant: You don't notice it, but the ant is killed. Let's now take a closer look at how organisms interact through their feeding relationships. Compare your sample with those of other groups. So where do fungi get their food from? These animals all eat insects and other small invertebrates. Filled with diagrams an animation in slides. Park rangers and conservationists work to save the environment. But, there are three different consumers in this food chain. In the article, wildlife is poached for the meat to be sold as food. Animals have different adaptations which have enabled different species to live and function in different areas. Shows the direction that energy flows and each If they can not find shade, they turn the body's lightest side to the sun. When the water droplets become big enough, they precipitate as rain. A key focus of the class is viewing soil health as the basis for ecological land management and discussing management practices to conserve and improve soils. Thanks. Only populations of organisms that happen to have suitable characteristics are able to survive in changing conditions within an environment. They notice that over the last 4 years, the population has grown quite rapidly. Based on the ruler provided for scale, the tapeworm appears to be over 25 feet long! Where would you place decomposers in a food chain? Interactions Within the Environment How do things "work" together to survive in their environments? This can be done as a short revision task in class or as homework to check what learners understand so far, or you can ask learners the questions orally in class. Write a definition below and then give four examples of animals from the images which are carnivores. The leaves have few pores to also minimise loss of water. Clipart and elements found in this PDF are copyrighted and cannot be extracted and used outside of this file without permission or license. Where does our waste from our homes go? A hummingbird feeding. Biotic Factors. Discuss this with your class. 1.2 The Roles of Producers If we put all the food chains within an ecosystem together, then we end up with many interconnected food chains. Some parasites cause familiar human diseases. In the last activity, we looked at different consumers. Natural disasters like floods or hurricanes can cause severe disruptions to ecosystems, but the ecosystems recover eventually. The concepts covered within the questions include abiotic factors, biotic factors, niche, ecology levels, species, population, community, & ecosystem. Follow the steps: Consumers have different sources of food in an ecosystem and do not only rely on only one species for their food. Habitat. In the area that you studied, was there any evidence of human interference? Use organisms from the ecosystem that you are studying at or near your school in at least two of the food chains you draw. I created an insert for Ecology Vocabulary Words. In each of the photos, the populations of animals are found in a specific area. It focuses largely on a few species studied in a lab setting. Includes PRINT and GOOGLE versions! It is completely laid out with teacher notes and a sequence of activities. Male ostriches get red beaks in the mating season. Chapter 3: Microorganisms Interactions and interdependence within the environment Chapter overview 5 weeks Learners are introduced to the basic concepts of ecology and the four levels in which ecological interactions are grouped for research and studying purposes. Any single living thing living within an ecosystem. Now let's make our own energy pyramids. Yes, it does make a difference. In the short term, many of the animals would battle as the zebra and the elephant would have a reduced food source, especially the zebra which eat grass. When Southern Africa rose out of the sea millions of years ago, organisms that could not adapt to the new, drier terrestrial environment became extinct, but individuals that could adapt, survived and formed new populations. Consumers are also called heterotrophs. It has a light, streamlined body with strong legs. (We will look more at balance in an ecosystem later in the chapter.). Biotic and abiotic factors Ecosystems are influenced by both biotic and abiotic factors. I'm adding new content on a weekly basis, so clic, Looking for human impact on the environment resources and reading passages to help your students understand this concept? This helps it to hide away from prey so that it can get as close as possible before chasing. For example, there are many different theories about why the dinosaurs become extinct. As soon as the flies land on the surface, the plant is triggered and the catchers clamp shut, catching the fly. The mouse creates its home in the ground/dead stick/grass, it can store seeds and food in the soil and hide from predators. (You will use this square to study different things in the next few weeks so make sure that you choose an appropriate site that does not overlap with another group's site.). Ecology: Name: Interactions Within the Environment Use the reading to match the vocabulary term with the appropriate definition. We will now put these different levels together in a hierarchical organisation representing the study of ecology. Password requirements: 6 to 30 characters long; ASCII characters only (characters found on a standard US keyboard); must contain at least 4 different symbols; Learning Tools, Flashcards, And Textbook Solutions | Quizlet, Classzone.com Has Been Retired - Houghton Mifflin Harcourt, TEACHING ENGLISH FOR YOUNG LEARNERS.pdf - Academia.edu, ASSIST | Australian School Science Information Support For , 2022-2023 List Of Courses | College Catalog, Chapter 1 - Ecosystem Interactions, Energy, & Dynamics, Interactions In Ecosystems - Springtown ISD. The website link provided in the visit box for our 'Breathing Earth' provides a very interesting simulation of how the population of the Earth, and also individual countries changes every second. How is the species adapted to life in its habitat? What do you think would happen to this ecosystem if all the zebra got a disease and died? It stores its water inside green succulent leaves and bloated branches. What sort of ecosystem does this food web describe? So autotroph means 'self-feeding'. In the previous illustration, we can see that the individual impala make up a population in the game reserve. Examples of herbivores are: elephant, duck, horse, buffalo, squirrel, grasshopper, rhino, zebra, cow, mouse, etc. Many species of animals display an interesting behavioural adaptation called migration. Why do you think these plants are commonly referred to as 'living stones' or 'pebble plants'? rainforest noun area of tall, mostly evergreen trees and a high amount of rainfall. Discuss this with your class. Does size in an ecosystem matter? Look for evidence of bigger animals. Animals who mistake litter for food often end up choking and dying. Measure the temperature of the soil about 5 cm below the surface. Ex: plants, animals (birds), insects (worms) 4. Community ecology is the study of how they interact. You can find out lots more online by visiting the links provided in the Visit boxes. Quizlet makes simple learning tools that let you study anything. How would they compare how well the penguins are doing in each population? The arrows show the direction in which the energy is transferred as one organism eats the other one, always from the producers to the consumers. Direct link to idchambers's post Competition Organisms of , Posted 4 months ago. This allows the plant to have a coloured, patterned upper surface to camouflage it from herbivores, but still allows that sunlight to travel through for photosynthesis. The arrow starting on the right above the buck should read 'Carbon dioxide released during respiration in plants and animals.' The arrow ending on the right below the buck should read 'Oxygen used by plants and animals during respiration.'. Anything that can limit the size of a population, including living and nonliving features of an ecosystem. Interactions and interdependence within the environment. place where an organism lives and that provides the types of food, shelter, moisture and temperature needed for survival. Habitat destruction is one of the main reasons, due to farming, fire and livestock (which may also may cause erosion), Other animal species compete for their food, Floods kill their young and destroy their habitat, They are killed in the road and by 4x4 vehicles in river beds, Hunters accidentally kill them, thinking they eat crops. They might not necessarily all die, but the numbers would decline. This includes climate changes, how the Earth has changed over history and even how the movement of planet Earth affects different ecosystems, wind patterns as well as rock and soil formation. Mutualism is a benefit to both, so it has to be a +/+, +/- is parasitism. The 6-E lesson format easily guides you through a variety of engaging activities. *This bundle includes information on the following topics: Symbiosis. @@BYhttp://www.flickr.com/photos/scubagirl66/7929201230/, Find where the grass is growing and there are water sources, The sardine run as sardines migrate along the South African coastline. Encourage learners to write the levels into the diagram. Explain your answer. Inappropriate waste disposal: Air pollution, Inappropriate waste disposal: Water pollution, Inappropriate waste disposal: Landfills and littering. How is this species adapted to life in its habitat? The last group of animals that we can discuss from this image are the decomposers. Write down below what these animals all eat and what we call this type of carnivore. They could say that decomposers would come at the end of the food chain as they break down the bodies of the dead organisms. During the course of Earth's history, many organisms have become extinct, so what is different and worrying about the decreasing numbers of rhinos and elephants? Type of Resource . Flowers grow between the leaves, which shrink to below ground level during drought. The survival of populations and species depends on whether enough individuals are suited to the environmental conditions at the time. It is well known that SA has undergone big climatic changes in the past. A number of Litter builds up and can take many thousands of years to degrade. Drought is water shortage, when there is no rain for a long time. Identify organisms and find possible relationships between them. Overview of competition, predation, herbivory, mutualism, commensalism, and parasitism. Isn't Amensalism among interspecific interaction? If you're seeing this message, it means we're having trouble loading external resources on our website. Tertiary Consumers: consumers secondary consumers to get energy. Why is a drought more likely to cause an imbalance rather than a month which receives a lower rainfall than usual? temperature, moisture, light, type During the investigations it is also important to walk between groups to ensure that they are applying the newly learnt skills appropriately and taking accurate measurements. In this case however, we have no plan B for planet Earth - there is no second Earth or any other planet that we can live on. Most of the leaf and hence the green chlorophyll is located on the underneath side of the plant underground. Next, fold the square in half the other way so that you have two folds diagonally across the square. Now that we know a bit more about the different biotic and abiotic factors in an ecosystem and how they interact, let's study an ecosystem! Which other types of organisms would you expect to find in this community, but you cannot see in this photo? How do organisms interact with one another and their environment? Human impacts on the environme, This fully editable Lab Station on the Interactions and Relationships Within Ecosystems is meant to get your students out of their seats and engaged in the content. Direct link to Alex's post It's a chain of interacti. Study of the interactions that takes place among organism and their environment. [2 marks]. Some will feel it's wrong to exclude people from traditional food sources, others feel it's more important to protect the animals and find other ways of helping people.
