This tutorial review over food chains and how energy is transferred through them.

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.

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

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.

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

Answer these ten interactive questions about ecological feeding relationships by choosing the correct image that completes each food 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.

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

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.

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

PBS site provides some basic information on the food chain.

In this lesson plan, students will choose an organism of their choice and research its life cycle, food chain, diet, and habitat, then predict how habitat change might affect the organisms living within it.

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

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 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.

Investigate the interdependence of wildlife in the Yellowstone ecosystem and draw an ecosystem showing the interdependence of life forms.

A module that explains what an ecosystem is and how energy and matter move through them. Students will look at the different roles of plants and animals and at ecological relationships in food chains and food webs.

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

Fun, interactive game that helps students identify interrelationships in an ecosystem. For six or more players.
