Fourth graders will be able to name some plants and animals that live in Utah's desert, forest or wetland ecosystems.

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,...

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

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.

In this lesson from "The Friends of Auntie Litter", (www.auntielitter.org), food webs and their significance will be explored. This lesson is one from the "Take Pride Statewide" series. *Lesson provided by Julie Danley and Pam Walston.

This lesson plan provides an eight-day flow of educational activities in which students use the Great Salt Lake ecosystem to explore food webs and how changes in living and nonliving factors affect different populations.

The difference between food chains and food webs is explained.

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...

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

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

[Free Registration/Login Required] In this interactive you will need to design a food chain that corresponds with the correct ecosystem. You will need a sign-in to access the media but it will be well worth your time!

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

Learn how scientists classify different types of organisms in an ecosystem or in a food chain by their role and function as either a producer, a consumer, or a decomposer. Then play a game that tests your understanding of these important...

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

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

[Free Registration/Login may be required to access all resource tools.] Understand what trophic levels are and identify producers and consumers in a food web.

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 collection of three lessons where students learn about abiotic factors in marine ecosystems, about marine food chains and biodiversity, and about marine food webs and trophic levels. Includes handouts, website links, and a vocabulary...

Understand how organisms acquire energy and how that energy is passed from one organism to another through food webs and their constituent food chains.

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...

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...

In this instructional activity, 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.

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.
