Name: Food Web Project Goal: Create a food web based on a chosen ecosystem, with at least 3 food chains that interlock. 1. You will prepare a food web for a selected region showing the connections of at least 12 organisms in that region. You can use pictures, print outs or drawings to show the connections between the organisms you selected. 2. From your food web write out 3 food chains and label each organism as either producer, primary consumer, secondary consumer, or decomposer. 3. Choose one of your food chains and make a pyramid of biomass with those organisms. 4. Use arrows to show the direction of energy from one item to the next. Some items may have more than one arrow coming to it or leaving from it 5. Detailed descriptions of each item. State the name of the item. Include if this item is an omnivore, herbivore, or carnivore. This would also be a great place to include if your item is a decomposer, consumer, or producer. Is it living or nonliving? The possible regions you can select your organisms include: grassland, desert, tropical rainforest, taiga, deciduous (temperate) forest, ocean, freshwater, and the tundra. Below write in your selected region and list the organisms you will use to make your food web. Selected Region: Organisms being used: Presentation: Your presentation may be completed in any manner you chose. If your presentation requires materials, you must bring them in to use during class. Do not forget you must present in front of your classmates. Follow the rubric for all projects. Below are some suggested ways to present: Poster, Mobile, Diorama, Brochure, Report, Speech, Play Questions Sheet 1. Identify 3 herbivores from your food web. 2. Identify 3 carnivores from your food web. 3. Are there any omnivores in your food web? What are they? 4. Where would the decomposers be placed in your food web? 5. What role do decomposers play in a food web? 6. Does the food web illustrate a population, community, or ecosystem? 7. Are the food webs or food chains more stable? Explain. 8. Name 3 abiotic factors that could affect your food web. 9. How does the nitrogen cycle play a role in recycling materials in your food web?
