Food Chains & Food Webs

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

Junior ecologists relate how food chains and food webs route matter and energy through an ecosystem. They trace feeding levels of a food chain or food web through a pyramid of energy. As a reinforcement activity, learners construct three...

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

How come we don't eat worms, but we eat fish that eat worms? A video features the food chain and explains why a food web is a better explanation for biodiversity. It includes explanations of producers, autotrophs, consumers,...

Who eats who in the savannas of Africa? Explore trophic levels with part four of an eight-part series of lessons focused around Gorongosa National Park. After young explorers identify animals using trailcam images, they construct a food...

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...

Investigate desert biomes by creating food chains and food webs. Groups first research feeding habits of organisms in the Sonoran Desert. This information helps pupils draw food chains and webs to determine relationship between organisms.

Feast on an informative resource. Scholars learn about food chains and food webs and how these interactions give information about the natural community. A PowerPoint presentation provides information about this concept.
