Bio-degradation is an example of a decomposer recycling organic compounds back into the environment.
EXPLANATION:
Biodegradation is a process which occurs naturally when chemical breakdown of the dead animals and plants is conducted by the microorganisms like bacteria and fungi.
This is initiated with the secretion of certain enzymes by these organisms.
Biodegradation causes the breakdown of the wastes products and remains of dead organisms, ad avoids their piling up.
It also releases 'valuable nutrients into the environment' for re-use by other organisms.
