This illustrated guide to food chains and ecological pyramids will help clarify how energy flows through an ecosystem.

Explains what biomass and energy pyramids are and provides a table highlighting their differences.

Explains the roles of consumers, producers, and detrivores or decomposers and how energy flows through the different levels of the energy pyramid of a tropical rainforest.

Explains the processes by which energy flows through an ecosystem. Covers the meanings of key vocabulary, e.g., types of producers and consumers, trophic levels, food webs, and the energy pyramid.

Review the flow of energy through ecosystems with this study guide.

Explore the different ecological roles of organisms in the ecosystem, and find out how the energy flows through them.

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

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