Q:

What role does photosynthesis play in the carbon cycle?

Answer

In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy.


Carbon :


coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose.


Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen


Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.


 


Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2.
