Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

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.

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...

[Free Registration/Login may be required to access all resource tools.] Videos, texts, activities, and assessments about food chains and food webs in an ecosystem.

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.

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

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...

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

Learners analyze food chains, webs, and pyramids to determine how energy flows and matter cycles through ecosystems.

This Museum of Science page does an excellent job of explaining the importance of plants as producers in the sea. The food chain or food web has to start with the plants.

In this lesson, 4th graders use tableaux to dramatize their roles in the food chain of an ecosystem. Next, they write in role arguing why they are important to the ecosystem. This is followed by a debate in the format of a Character...

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 middle schoolers use the Great Salt Lake ecosystem to explore food webs and how changes in living and nonliving factors affect different populations.

[Free Registration/Login may be required to access all resource tools.] Producers make their own food through photosynthesis. But many organisms are not producers and cannot make their own food, but must get their energy from other...

[Free Registration/Login may be required to access all resource tools.] Discusses how autotrophs and heterotrophs obtain energy.

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

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...

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

The Web of Life is a story told by a common garden spider at this site from Kids' Planet. Learn about the food web, and the roles and relationships of every living creature.

Work samples, phenomena, assessment templates, and videos that directly address standard 5-PS3-1: food energy from the sun.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-LS2-3: matter cycling and energy flow in ecosystems.

[Free Registration/Login may be required to access all resource tools.] Energy must constantly flow through an ecosystem for the system to remain stable. What exactly does this mean? Essentially, it means that organisms must eat other...

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.
