The following is a tutorial of food chains, food webs and food pyramids.

This lesson, supported by the provided power point lecture (LESSON 1 and 2 Ecology Lecture Supplement ), introduces students to the concepts of food chains and food webs. Through its use, students learn the difference between producers...

Students 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.

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...

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...

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

[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.

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

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...

Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and...

[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.

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, students examine how overfishing has affected Chesapeake Bay's ecosystem. They will study food webs from the past and present and graph related data.

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

Food webs lesson, which focuses on Chesapeake Bay habitats, integrates biological concepts with literacy knowledge and skills. Lesson directs students to answer the question, how does a human-caused stress placed on the environment...

[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...

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.

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.

This lesson will explain how to create a food web to show transfer of energy within a community. It is 1 of 4 in the series titled "Food Webs."

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

Trace the energy transfer through food chains and food webs. Check your understanding by hovering your mouse over questions to reveal the answers.

Discover how energy flows as part of a food web. Identify the ultimate source of energy for organisms on Earth.

Investigate some animals and see where they are in the food web. Build your own food web and relate it to the endangered species biomes.

Authors provide an explanation of the taiga biome and information on the threats to the future of the taiga as well as a terrestrial food web.
