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...

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...

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and...

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...

Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

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

Students learn about the feeding relationships in an estuary ecosystem with this interactive energy pyramid activity. A second activity involves research and a video clip to elaborate the learning.

Read to understand how energy and inorganic nutrients flow through a food chain in an ecosystem.

Kids learn about the food chain and food web. How energy cycles and transfers through living organisms.

This is a hands on lesson in which students will explore their local community to identify living things. It can be used as part of a unit on biodiversity and energy transfer within a biology, zoology, or environmental science course, or...

Describes how a food chain works in a desert and how the Mojave desert food chain works in particular.

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...
