By converting carbon dioxide and water into glucose and oxygen, providing energy and organic compounds for living organisms.
B
By converting nitrogen gas into ammonia, which is essential for protein synthesis.
C
By producing ATP directly from sunlight, which is used as an energy source by all organisms.
D
By breaking down glucose into carbon dioxide and water, releasing energy for cellular processes.

Photosynthesis is a process that occurs in plants, algae, and some bacteria, where light energy is converted into chemical energy stored in glucose.
In the context of organic chemistry, photosynthesis involves the conversion of carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2) using sunlight. The overall chemical equation can be represented as: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
The glucose produced serves as an energy source and a building block for other organic compounds, supporting the growth and metabolism of living organisms.
Oxygen, a byproduct of photosynthesis, is essential for the respiration of most living organisms, allowing them to release energy from organic compounds.
Photosynthesis is crucial for maintaining the balance of oxygen and carbon dioxide in the atmosphere, supporting life on Earth by providing energy and organic compounds necessary for survival.
