How does photosynthesis in plants affect the carbon cycles

Photosynthesis by land plants, bacteria and algae converts carbon dioxide or bicarbonate into organic molecules.

Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas.

Hence affecting the carbon cycle.
