Answer 1

Living organisms return carbon back into the atmosphere primarily through decomposition and respiration.

• Respiration: During respiration, organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct, which is then returned to the atmosphere.

• Decomposition: Decomposers break down dead organic matter, releasing carbon back into the atmosphere in the form of carbon dioxide.

So, the correct response is decomposition and respiration.
