State
A biogeochemical cycle moves matter, such as carbon atoms, repeatedly between organisms and environment, per Bio 0612 — no cycle returns dissipated energy.
Show
An exhaled carbon atom can be re-fixed and eaten again; the light energy that powered fixation cannot be recovered.
Watch for
"Ecosystems recycle their energy," per Bio 3653, mistakes matter cycling for a process, per Bio 0612, energy never undergoes.
