and energy move through an ecosystem. This
is what they said:

Morrie: "I think only energy cycles through
an ecosystem

Feliciar "I think only matter cycles through
an ecosystem

Stefano: "I think both matter and energy
cycle through an ecosystem.

Lincoln: "I think neither matter nor energy
cycles through an ecosystem
