Photosynthesis is the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. This process involves capturing sunlight, carbon dioxide, and water to produce oxygen and glucose as a byproduct.
Photosynthesis is essential for life on Earth as it is the primary source of oxygen in the atmosphere. It also serves as the foundation of the food chain, as plants are the base producers that provide energy for all other organisms in the ecosystem through the food they produce. Additionally, photosynthesis helps regulate the levels of carbon dioxide.
