Abstract

The goal of this laboratory exercise is to provide a hands-on introduction to food webs, nutrient cycles and energetics. Combining owl pellet dissection and a low stakes food/energy web activity allows students to observe and handle tangible evidence of energetics before constructing a more complete picture. It also provides an opportunity for students to incorporate alternative food and nutrient webs into their concept of energy flow through an ecosystem. This exercise is designed for students at multiple levels and to work at a range of class sizes.
