2. In this process, the energy (ATP-Adenosine triphosphate) is produced by the breakdown of glucose.
3. Energy is further used by cells to perform various functions.
4. While photosynthesis is a process by which phototrophs convert light energy into chemical energy, in the presence of sunlight, CO₂, chlorophyll, etc.
5. Hence, the air is essential for the continuity and survival of life as its constituents are needed for two very important biological processes, namely respiration, and photosynthesis.
