SCENARIO: Humans are consumers. We obtain our energy from the sun secondhand (at least). Think about what a food chain would look like if you were the top carnivore, and you were eating a tuna sandwich. Where did the original energy in your sandwich come from? How many trophic levels did that energy pass through. Think about this scenario as you answer the following questions. Please refer to your textbook, section 36.1, and use it as a resource to answer the following questions.
Questions to Answer:
Using the information in your textbook, and the example of you (a human) eating a tuna sandwich, explain the following:
1. How does energy flow in your food chain?
2. How many trophic levels are used to get a sandwich of smelt (tuna)? Give an explanation to support your answer.
3. What was the original source of energy in your food chain? What type of organisms were producers in your food chain?
4. Which organisms were consumers in your food chain?
5. Are food webs as complicated as food chains? Why or why not?
