This lesson will explain how to create a food web to show transfer of energy within a community. It is 1 of 4 in the series titled "Food Webs."

A video and a short multiple-choice quiz on food webs that explains the difference between food webs and food chains, and the relationships that exist between organisms.

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

Learn about food webs, food chains, and organisms interactions in this interactive tutorial.

Food webs lesson, which focuses on Chesapeake Bay habitats, integrates biological concepts with literacy knowledge and skills. Lesson directs students to answer the question, how does a human-caused stress placed on the environment...

Discover how energy flows as part of a food web. Identify the ultimate source of energy for organisms on Earth.

Two differentiated tasks about food chains and webs. In the more challenging task, students construct a food web to show the relationship of the animals and plants in a given environment. In the lower level task, students create a food...
