A video workshop examining how the Sun provides energy for all living things beginning with the process of photosynthesis. Presents current scientific thinking about energy transfer through the food chain as well as ways to deal with...

Describes how a food chain works in a desert and how the Mojave desert food chain works in particular.

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

Describes the characteristics of a tundra biome, how a tundra food chain compares to a tropical food chain, and what the different trophic levels look like.

This lesson explains the role plants play in the conversion of inorganic materials into organic material to support living things. It is 2 of 3 in the series titled "The Role of Plants in the Food Chain."

This lesson explains the role plants play in the conversion of inorganic materials into organic material to support living things. It is 3 of 3 in the series titled "The Role of Plants in the Food Chain."

Explains what a primary consumer's role in a food chain is and provides examples.

This activity allows students 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.

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.

For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...

Young scholars construct possible food webs for six different ecosystems as they learn about the roles of producers, consumers, herbivores, carnivores and decomposers.

Lesson plan to construct and explain a food chain. Includes games and activities to teach and reinforce concepts.

Discussion of what makes up a food chain and its significance. Includes some historical perspectives on developing the concept, and on how a pesticide called DDT affected food chains during the 1960's.

This animation discusses the food chain in a storybook format. The chain is described as a cycle and both herbivores and carnivores are discussed.

A very informative site that discusses food chains and webs in detail. Not too complicated and fairly easy to understand, it also includes some pictures.

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

PBS site provides some basic information on the food chain.

Students will use a card sorting activity to construct a food chain and identify the role of organisms within that chain. The cards represent different individuals in an ecosystem and will help students begin to understand the concepts...

[Free Registration/Login Required] This flipchart reviews various food chains.

A lesson that helps students understand food chains and food webs. With the background information, interactive activity, and extensions, students will see the interconnectedness and interdependence of organisms. Activity has students...

[Free Registration/Login Required] This flipchart allows students to identify and manipulate food chains.

In this ecosystem consisting of hawks, snakes, rabbits and grass, the population of each species can be studied as part of a food chain. Disease can be introduced for any species, and the number of animals can be increased or decreased...

[Free Registration/Login Required] Through this flipchart students will be able to summarize and organize simple food chains.

In this unit students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the health...
