Biology

1. Which organism in the food web above is sometimes a first-level consumer
and sometimes a second-level consumer? Explain.
2. Choose one food chain in the web. Name all the organisms in that chain.
Start with the producer and end with the top-level consumer.
3. Draw an energy pyramid for the food chain you chose. Label the pyramid to
tell how much food energy is available at each level.
