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.
