Which processes reduce the amount of carbon dioxide in the atmosphere

The process that reduces carbon dioxide from the atmosphere is photosynthesis.

In the process of photosynthesis, carbon dioxide is taken from the atmosphere in order for the plants to create oxygen for humans and other species that require oxygen. The cycle is then repeated when humans exhale carbon dioxide and inhale oxygen, giving back the carbon dioxide to plants and inhaling the plant emissions.

Therefore, the process is photosynthesis.
