1. Draw a food web for a terrestrial ecosystem. Include at least 6 organisms: producers, primary consumers, secondary consumers, a top predator, and decomposers. Use arrows to show energy flow (from food to eater).

2. Label each organism you included. List the organisms and their trophic level (producer, primary consumer, etc.):

3. In one sentence, describe how energy flows through your food web (which direction do arrows point?):

4. Check all organisms below that are producers (make their own food using sunlight):

5. Match each organism (left) with its role (right). Draw a line to match.

6. For two organisms below, write one sentence each describing their role in the ecosystem.

a) Oak tree:

b) Fox:

7. Explain in one sentence why decomposers are important to ecosystems:
