Ecosystem Model Project Your Goal: To make an ecosystem (diorama/ model) showing how an ecosystem works. Organisms must have the necessary resources in the ecosystem to maintain their existence. Part A – The Ecosystem 1. Choose an ecosystem (forest, desert, coral reef, ocean, rocky shore, grassland, mountain, savanna, prairie and pond etc.) to study independently. Focus your research on the main biotic and abiotic elements in the ecosystem. Do some research as to what plants and animals live in your ecosystem and how they interact with each other (in other words - who eats who!) 2. Brainstorm: Create a T-chart (sample below) or graphic organizer to help you sort your findings into the following categories: 1) Abiotic 2) Biotic: Plants and Animals (herbivores, carnivores, omnivores). * Be as specific as you can when naming your elements (i.e. Toucans vs. bird, Deciduous Tree or pine tree vs. tree). *Hand in to the teacher before you begin your model. ABIOTIC BIOTIC Plants Herbivore Animals Omnivore Carnivore 3. You need to find a minimum of at least 3 abiotic elements, 3 plants, 3 herbivores, 3 omnivores and 3 carnivores in the ecosystem. 4. Once you have gathered all of the information, begin to create your model ecosystem. You can start by drawing or creating the landscape. This is best done by colouring in the background or the inside of the box (for the model). You may want to colour in paper and cut it out to stick into the model box or you may wish to paint or use other materials to create the landscape. Then create or draw, colour in and cut out the various animals and plants. Cut them out and stick them onto the background as they would interact. 5. You must LABEL the name of each element in your ecosystem. (What [species] is it?) Due Date: _______________________ Part B – Interactions in the Ecosystem Throughout this unit, we have been examining how an organism interacts with the living and nonliving elements in an ecosystem. We have discussed and investigated predator/prey relationships as well as food chains and webs. Now it is time to put that knowledge into practice and explore some of the interactions between different components in your ecosystem. Your Goal: Using your model ecosystem and generate one food web on a poster/flyer. 1. Using your model, create 1 food web that contains at least 8 elements. Display this web on a separate piece of paper. (Remember to include producers, primary consumers, and secondary consumers.) They must be realistic feeding relationships! ** A food web contains many food chains; make sure your consumers have a variety of food to eat. ** 2. On your food web ‘poster’ - label whether each living thing is a producer or consumer. 3. Each consumer must also be labeled as a herbivore, carnivore, omnivore, or decomposer. 4. Draw all the connections within your web using an arrow between the elements to show the flow of energy. (Show where the energy is going.) Part C – Presentation 1. You will present your model and food web to fellow students, to demonstrate what you learned about your ecosystem. Use the following questions to help you develop a good project. □ Is your name on the front of the project? □ Is the ecosystem type easily identified? □ Is the model a 3D representation of an ecosystem? □ Are all the elements included? o (at least 3 abiotic elements, 3 plants, 3 herbivores, 3 omnivores and 3 carnivores) □ Is your ecosystem model neat and made with attention to detail? □ Are the elements correctly labeled? Each element must be labeled with its name. □ Are the food web elements correctly labeled? □ Is the flow of energy shown within your web using an arrow? □ Is your food web neatly constructed and easy to follow?
