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.

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

Connect the dots to investigate three different habitats either the forest, bai or river of the rain forest. By connecting the dots students make a food chain to see how organisms in each habitat depend on each other.

Think and Link to investigate three different ecosystem either the deep sea, coral reef or continental shelf. By connecting the dots students make a food chain to see how organisms in each habitat depend on each other.

[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.

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...

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

This resource provides information about ecology.

Join Ellen on her trip to the Kaap De Goede Hoop in South Africa, and learn more about plants, animals, and energy.

In this activity, students will learn how changes in nature can be beneficial or harmful to animals. At the end, students will be able to conclude information according to the evidence collected.

A colorful tutorial about ecological pyramids. Read the information, and then check your understanding with some questions and answers about the topic.

[Free Registration/Login may be required to access all resource tools.] When an herbivore eats a plant, the energy in the plant tissues is used by the herbivore. Every time energy is transferred from one organism to another, there is a...

This interactive ebook "Pond Web" demonstrates a pond food chain. Students can click on the ? to find answers to questions posed in the text. Students are asked to retell the story using pictures provided at the end of the book.

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.

Explore the different ecological roles of organisms in the ecosystem, and find out how the energy flows through them.

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.

[Free Registration/Login may be required to access all resource tools.] Understand how energy flows within ecosystems through the use of energy pyramids.

[Free Registration/Login may be required to access all resource tools.] Based upon the way organisms acquire their energy students will understand how to group them as consumers, decomposers or producers.

A complete lesson on owl pellets. Students can read information, watch a tutorial, and use their computer mouse to complete a dissection simulation right there on the screen.

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