Answer 1

Photosynthesis and the respiration is a cycle which balances the level of gas in the atmosphere. Boussingault (1860) reported that the volume of CO $_{2}$ absorbed is equal to the volume of O $_{2}$ released. During the process of photosynthesis, the raw materials required was first explained by Boussingault.
