Answer:
Photosynthesis play important role in the cycling of matter into and out of the organisms as photosynthesis is the process in which plants utilize carbon dioxide (CO2) and water (H2O) and releases oxygen (O2) and energy in the form of carbohydrate or sugar. Other organisms utilizes these oxygen and energy or carbohydrate for the chemical reaction in their body.
So, photosynthesis take carbon dioxide (CO2) and water (H2O) from outside as input and gives oxygen (O2) and energy as output.
