Complete the following analysis and record your responses to the questions in the space provided below. Based on the list of organisms you collected, start to build your food web here. Draw or scan in your picture. When building your food web, consider what the organism eats or how it produces food. If you are not sure, research this particular organism and make your best guess. You must include ALL of the organisms which you have listed above in your food web. Do your best. This is just an initial view of the food web relationships in your ecosystem. In your food web, why does the arrow point toward the consumer? Explain. Analyze the information you have collected in your data table and constructed in your food web. What type of organism is most common? Are they producers, consumers, or decomposers? How about herbivores, carnivores, or omnivores? Explain why you think this is the case. What might occur if one of these species in your food web was removed? Explain. You may even consider redrawing your food web to help support your answer. What might occur to this particular food web if a new species was introduced? What if it was a producer, a consumer, a scavenger or decomposer? Support your answer by discussing at least two of these possibilities. How is a food chain different than a food web? Support your answer by creating a small food chain based on the information you collected in this laboratory. Based on your food web, create a trophic level pyramid. Add as many organisms to the trophic level pyramid as possible. Below the pyramid, explain in a short paragraph why you placed the organisms in a specific level with respect to energy flow. Refer back to your initial hypothesis. Did you support your initial hypothesis? Why or why not? Explain.
