FOOD WEBS

Let's take a closer look at the parts of a ecosystem. One major component is its unique food web. The food web, is how energy, in the form of food, is transferred from plants to animals to other animals. Food web diagrams and models are used to understand how the natural ecosystem functions.

Today, we are going to explore the parts of a food web. Plants and animals form different levels and serve different functions.

First, complete this activity. At the end, click on Return to Food Chains and Cycle Index and take the test to review.

Second, draw a food web based on the two habitats you researched in the previous lesson.

Make a chart in a Word document and turn it into a diagram of a food web.

Include these key words in your chart: producer, consumer, decomposer, primary (1°) consumer, secondary (2°) consumer, tertiary (3°) consumer.
