Importance of Photosynthesis
Photosynthesis is a crucial energy-converting process by which plants produce molecular oxygen and carbohydrates by the use of photons present in the light. The natural source of light, the sun, helps the green colored plants to fix the atmospheric carbon dioxide in to usable molecular oxygen, that we humans happen to breathe.
They help in maintaining a balanced level of oxygen and carbon dioxide in the atmosphere. Almost all the oxygen present in the atmosphere can be attributed to the process of photosynthesis, which also means that respiration and photosynthesis go together. Also, the chemical energy stored in plants is transferred to animal and humans when they consume plant matter. Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.
