The two processes that remove carbon dioxide from the atmosphere are photosynthesis and absorption. Respiration and volcanism, or the eruption of molten rock, are the two processes that provide carbon to the atmosphere.
carbon is removed from the atmosphere through photosynthesis and replaced with O2. O2 is removed from the atmosphere during respiration and replaced with carbon . These processes, however, are not in equilibrium. Not every organic substance oxidizes. Photosynthesis and metabolism are the two fundamental processes that take place during the natural carbon cycle. Plants consume carbon dioxide during photosynthesis to create oxygen, and they also make carbon dioxide during metabolism.
