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

This activity allows learners 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.

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...

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

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

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

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.

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...

In this unit students 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 health...

This unit on matter cycling and photosynthesis has students investigating the idea that all food comes from plants.

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

Detailed explanation of the processes by which energy flows through an ecosystem. Scroll down and open Section 3.

This module offers an in depth study of the fundamental components of ecosystems. Activities include mini-lessons with videos and student assignments.

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles....

[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.

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

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.
