Ecology: Food Chains and Trophic Levels

Ecology: Food Chains and Trophic Levels

1. Approximately how much energy would each consumer gain in the following food chains? (Label)

a) b)

2. Approximately how much energy would you gain as a tertiary consumer if the producer had converted 2532 J of radial energy into chemical energy? Draw a diagram and label each part.

3. Approximately how much energy would each organism in a fourth trophic level food chain gain if the animal at the third trophic level gained 4300 KJ from the previous organism? Draw and label the food chain.

4. Approximately how much energy would you gain as a secondary consumer if the primary consumer had converted 777.3 J of radial energy into chemical energy? How much energy would the producer have had?

5. A few food chains depend on sources of energy other than the Sun. Give an example by drawing this food chain.
