Photosynthesis is a vital biological process through which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. It involves taking in carbon dioxide and water and releasing oxygen as a byproduct. This process is fundamental to life on Earth as it forms the base of most food chains.
