Overview

This lesson will help students visualize the interconnections found within the natural world. They will learn the concepts of food chains and food webs, and construct their own food web using the provided worksheet of plants and animals found in Theodore Roosevelt National Park.

Objective(s)

Students will be able to explain how energy is transferred between organisms. They will also create a model showing this energy transfer, and explain the importance of diversity in an ecosystem.

Background

Plants and animals are connected in a complex array of interdependence known as a food web. Individual relationships can be depicted through simple food chains, and all organisms depend on these relationships for acquiring the energy they need to live. The vast array of plant and animal life found in Theodore Roosevelt National Park is an ideal example for students to learn about food webs and energy transfer through the ecosystem.
