When there is too much carbon in the atmosphere, the hydrosphere mainly oceans, absorb most of it to balance it

out.

Explanation:

Hydrosphere refers to the water portion of the earth. Usually, living organisms particularly animals that live on land and water breathe in oxygen and give off carbon dioxide, thus increasing the carbon dioxide levels in the atmosphere. Then the carbon dioxide is abundant in the atmosphere, and gets dissolved in water bodies (hydrosphere) particularly the oceans as the ocean waves sweep over large distances.

Thus, carbon dioxide is always in balanced proportion in nature
