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.

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

Kids learn about the food chain and food web. How energy cycles and transfers through living organisms.

Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

Starts with living and non living and works through producers, consumers, food chains and food webs.

Omnivores, herbivores and carnivores are waiting for you. The food chain comes to life at this friendly site.

This unit contains interactive lessons on animal ecosystems, animal classification, adaptations, and food chains.

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.

Learn how energy is transferred through the food chain.

This activity allows young scholars to make a simple model food chain and observe how toxic chemicals can become concentrated in the bodies of consumers at the top of the chain.

Learners 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.

Understand how the food chain works within ecosystems.

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.

Students 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 illustrate...
