Contributor: Meghan Vestal. Lesson ID: 11005

You've heard of spider webs, but a food web? Is it made by a special spider that captures hamburgers and tacos? No, it's a way that energy gets from the sun to a worm. Read on to see how it all works!

Audio:

The image above depicts important information about an ecosystem. Can you determine exactly what the image shows us about an ecosystem? Think "menu"!

In the previous Living Organisms lesson, Living Organisms: Producers, Consumers, and Decomposers, you learned what producers, consumers, and decomposers are.

In this lesson, you will learn more about how these organisms interact with one another in their environment.

Food webs, like the one pictured above, help us to understand how producers, consumers, and decomposers interact, by showing how energy is transferred within an ecosystem. All food webs start with the sun because it is the basis of all energy in an ecosystem. From there, the arrows show how the sun’s energy is transferred to each organism in an ecosystem.

Learn more about food webs by reading Idaho Public Television’s Food Web: Facts. You can also click on the different tabs at the top of the page to watch videos and read more articles about food webs.

Then, watch this Crash Course Kid’s video to learn why food webs are important and what can happen to an ecosystem if one part of an ecosystem’s food web is out of balance:

Food Webs: Crash Course Kids #21.2:

 

After you have watched the video, discuss with a teacher or parent why food webs are important.

  • What types of organisms make up a food web in your community?
  • What would happen if one of these organisms were removed from the food web?

Continue on to the Got It? section to interactively create a food web!
