Explains the characteristics of food chains and food web; the different levels of producers, consumers, and decomposers; and the differences between food chains and food webs. Includes charts and a Venn diagram comparing the two.

Read about the different predators, consumers, and producers that make up an ocean food chain.

A video and a short multiple-choice quiz on food chains that explains how energy flows through the chain, beginning with plants.

[Free Registration/Login Required] An informational text explaining important vocabulary involving the food chain. A question sheet is available to help students build skills in reading comprehension.

Use this TED Ed lesson, complete with video, questions, and links to resources for deeper understanding, to introduce the food chain.

Learn how energy is transferred through the food chain.

Learn how energy is passed along through living things in a food chain and web.

[Free Registration/Login may be required to access all resource tools.] Describes how food chains represent feeding relationships.

View examples and learn how animals impact the food chain.

Have a look at a simple food chain and others that are more complex. Then construct a series of food chains by playing a drag-and-drop game.

Understand how the food chain works within ecosystems.

This illustrated guide to food chains and ecological pyramids will help clarify how energy flows through an ecosystem.

Take an interactive quiz over food chains. After completing the quiz, check your score, and then revisit any incorrect question for further review.

Brush up on food chain vocabulary before taking this interactive quiz. Check the box for the correct answers throughout the assessment.

Young scholars begin this lesson by making observations and recording evidence of the variety of living things in local nature site. Students use reference materials to research predators and food of the animals they observed, then...

Students will build a food web diagram and illustrate the movement of matter through a series of food chains. Resources include detailed plans, examples of student work, videos of the lesson in action, and sample food webs.

Explore the food web in a coral reef with these illustration. Identify the consumers, producers, and decomposers that are located within this ecosystem. Site includes illustration exploring the different food chains as well as questions...
