Question

Explain in detail how photosynthesis follows the law of conservation of mass AND the law of conservation of energy.

Answer 1

The law of conservation of mass states that in ALL chemical reactions, matter is neither created nor destroyed. The law of conservation of energy states that in ALL chemical reactions, energy is neither created nor destroyed. Photosynthesis is a chemical reaction so it must obey the above laws. You can see that no mass is created or destroyed because all the atoms present before the reaction are present in the same quantities after the reaction. No energy is created or destroyed either. Light energy is simply converted into chemical energy.
