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?
