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

In this unit young scholars 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...

Two differentiated tasks about food chains and webs. In the more challenging task, middle schoolers construct a food web to show the relationship of the animals and plants in a given environment. In the lower level task, students create...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

Visualize how energy transfer takes place in two linked food chains, and how it demonstrates the interdependence organisms of the Great Salt Lake.

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.

This lesson focuses on food chains in ecosystems, including levels of consumers, decomposers, and a list of common words used with food chains and their definitions. It also provides a link to an assessment.

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

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...

The difference between food chains and food webs is explained.

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from...

[Free Registration/Login may be required to access all resource tools.] A close look at how animals and the environment interact with one another and specifically how the feeding relationships in a food web.

The students will become the food web in this fun interactive classroom activity. Detailed instructions, background information, guiding questions, and activity worksheets are provided.

A comprehensive overview of food webs. Includes three videos: a half-hour show, a video short, and a short video where an expert answers children's questions. Other features of the site include facts, links, games and activities, a...

In this comprehensive lesson unit, young scholars examine how overfishing has affected Chesapeake Bay's ecosystem. They will study food webs from the past and present and graph related data.

Jorge is a cook in an underwater restaurant. He knows a lot about food webs. Dive in and learn about it with him.

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

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.

A collection of three lessons where young scholars 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...

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

[Free Registration/Login may be required to access all resource tools.] Students will recognize and understand the role of producers in the food chain within different ecosystems.

[Free Registration/Login Required] This flipchart is a great introduction to ways animals get food, characteristics of animals, habitats around the world. It contains pictures that will help students understand life cycles and where to...
