The process by which increased levels of CO2 in the atmosphere lead to enhanced growth of vegetation, which then removes CO2 from the atmosphere through photosynthesis is termed a .

Carbon cycle

Explanation:

Carbon cycle refers to the interconversion of carbon and its compounds from one form to another in nature. It helps to bring balance to the amount of carbon compounds in nature.

Thus, through the process of respiration plants take in atmospheric carbon dioxide (CO2) into their stomata, giving off oxygen as by-product. While during photosynthesis, CO2 is used to produce sugar molecules such as glucose, that are consumed by consumers.

it's filtration, but this is an assumption so my apologies if i got this
