Students look at the data maps given to them about how chlorophyll affects the algae blooms and make predictions about the harm they will cause. In this data maps lesson plan, students manipulate data sets from the website.

Students explore the predator-prey relationship using an interactive game. In this biology instructional activity, students compare their physical attributes. They explain how  predators develop to make it stronger and efficient as...

Students investigate the decomposition process. In this ecology lesson, students participate in a play, "Up the Treehouse" where the main idea focuses on a decomposing tree and how food chains are effected by decomposition. After the...

Young environmentalists study the effects that pesticides have on birds, such as the peregrine falcon. They also look at predator/prey interactions. Some wonderful in-class activities accompany an inventive instructional activity. After...

Students explore the physical characteristics, distribution and habitat of termites. The lesson plan focuses on the termite as a social creature contrary to most other insects.

Learners 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.

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.

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...

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

Explains what a food web is, the complexity of one in a rainforest, and how energy flows through a food web.

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

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 resource provides information about ecology.

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.

Learn how scientists classify different types of organisms in an ecosystem or in a food chain by their role and function as either a producer, a consumer, or a decomposer. Then play a game that tests your understanding of these important...

Take an interactive quiz over food chains. After completing the quiz, check your score, and then revisit any incorrect question for further review.

Brush up on food chain vocabulary before taking this interactive quiz. Check the box for the correct answers throughout the assessment.

Students begin this lesson by making observations and recording evidence of the variety of living things in local nature site. Students use reference materials to research predators and food of the animals they observed, then illustrate...

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

Lesson plan to construct and explain a food chain. Includes games and activities to teach and reinforce concepts.

Describes the characteristics of a tundra biome, how a tundra food chain compares to a tropical food chain, and what the different trophic levels look like.
