Food Chain And Food Web Worksheet Answer Key

What is a Food Chain?

A food chain is a linear sequence of organisms through which energy and nutrients flow from one organism to another. It is a single pathway through which energy and nutrients enter the environment and move from one organism to another. The sequence of organisms in a food chain is known as a trophic level. The first organism in a food chain is usually the producer, which is usually a plant, and the last organism is usually the consumer, which is usually an animal.

What is a Food Web?

A food web is an interconnected set of food chains. It is a more realistic depiction of the way energy and nutrients circulate in an ecosystem. Food webs illustrate the interdependence of organisms in an ecosystem and how they rely on each other for energy and nutrients. It also shows how energy and nutrients are lost through death, decay, and excretion.
