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

• Food 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 not energy.

• Food webs include how energy enters an ecosystem, and food chains don't.

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

  things.
