Overview

The world is composed of many natural ecosystems in which plants and animals interact with one another and the nonliving environment. Each species has a niche or job within the ecosystem and each is dependent on the other members of its community for survival. Students will explore the natural communities found in Shenandoah National Park and make comparisons between natural and human communities. As human and environmental impacts are evaluated, stewardship behaviors that support a healthy world will be explored and practiced.

Objectives

Following the park experience and classroom activities, the students will be able to

  1. define food web and explain the transfer of energy in a sample food web;

  2. determine an organism’s niche in its community and describe the interdependent relationships among organisms;

  3. identify at least three environmental and human influences that can impact a community and determine potential consequences;

  4. explain how Shenandoah National Park protects natural communities and list three ways people can demonstrate care for the environment.
