Try It Yourself!

Take a walk in a local park or just sit in your backyard. If you are observant and patient, you will most likely be able to identify at least one food web at work there. What organisms are eating which other ones? What hap- pens when an organism in this environment dies? Be sure to check out the producers, consumers, and decomposers in the food web.

Suggested Materials: Poster board

Colored pencils, markers Different colored yarn

1. Identify at least four different producers and four different primary and sec- ondary consumers in your environment. What are they?

2. Identify the source of energy in your food web.

3. What decomposers are working here? How do you know?

4. Draw the interactions between these organisms on the poster board. Use yarn to represent the flow of energy from the producers to the primary consumers to the secondary consumers.
