How Can You Model a Food Web?

Populations interact through feeding relationships. A food web shows overlapping feeding relationships in a community.

Procedure:

1.

On a colored sheet of paper, make a list of at least 10 different organisms within a community of your choice (ocean, lake, forest, etc.). Include a variety of producers, consumers, and decomposers.

2.

Use scissors to cut out the name of each organism on your list.

3.

Arrange the names on a piece of construction paper.

4.

Once you have them arranged correctly, glue them down.

5.

Use yarn and tape to connect the organisms that have feeding relationships. For example, a piece of yarn would connect a rabbit and grass.

Analyze and Conclude:

1.

How does the Sun play a role in the energy flow through an ecosystem?

2.

Imagine that you remove 3 organisms from your food web. How would this affect the other organisms in the food web?

3.

Why are decomposers important to the food web?
