Why are food webs better representations of how energy moves through an ecosystem than food chains?

• For chains include decomposers, which do not play a role in energy movement through an ecosystem.

• Food chains show how matter moves through an ecosystem, not energy

• For webs include how energy enters an ecosystem, and food chains do not.

• Food webs show that animals in an ecosystem can get energy by eating different things.
