Constructing A Food Web

Here is a practical activity for reinforcing understanding of energy flow in ecosystems. Learners identify whether each organism in a list is a producer or decomposer. They tell if each is an herbivore, carnivore, omnivore, or...

Tenth graders examine how energy is lost through different trophic levels.  In this trophism lesson students construct a food web and view a video. 

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...

What happens when a non-native species is introduced onto an island? Santa Cruz Island, part of the Channel Island chain located off the coast of southern California, provides the perfect laboratory for young environmental scientists to...

If you need a few basic activities for teaching food chains to your emerging ecologists, here they are. Three sheets of organism cards are included for learners to cut out and arrange according to trophic relationships. To make the most...

Middle and high schoolers examine the basics of a mountain lion's diet by examining food chains and food webs. Learners are each assigned one of the lion's prey species and they must construct a food chain for this animal. They see how a...

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...

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.

Young scholars explain the main concepts of food webs and food chains. They describe the role of animals, plants, and other organisms in cycling energy and matter through a food web by creating mobiles. Lesson contains adaptations for...

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.
