Quizplus · Accepted Answer

Dissolving and outgassing of carbon are physical processes that involve the exchange of carbon dioxide between the atmosphere and the ocean. These processes do not involve living organisms and are driven by physical factors such as temperature, pressure, and concentration gradients. The other options involve biotic processes such as respiration, photosynthesis, and trophic interactions, or abiotic processes involving the formation of calcium carbonate.
