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.
