Photosynthesis is essential for the survival of most life forms because it is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen. Glucose provides energy for the organisms to carry out their life processes, while oxygen is released into the atmosphere as a byproduct, which is crucial for the respiration of most organisms, including humans. Additionally, photosynthesis is the primary source of food and energy for almost all ecosystems on Earth, making it a fundamental process for the survival and maintenance of life forms.
