Which process primarily releases CO2 back to the atmosphere?

Explanation:
Respiration releases CO2 back to the atmosphere when organisms break down stored carbon to obtain energy. Photosynthesis, on the other hand, uses CO2 to build sugars and store carbon in biomass, acting as a sink rather than a source. Biomass storage means carbon is held in living or dead matter, which slows release but doesn’t actively put CO2 into the air. Condensation is a water cycle process and involves water, not carbon. So respiration is the process that returns CO2 to the atmosphere.
