Photosynthesis plays a significant role in the carbon cycle by converting solar energy into chemical energy while removing carbon dioxide from the atmosphere. During this process, plants, algae, and certain bacteria utilize sunlight to transform CO2 and water into glucose and oxygen. This not only provides essential energy for autotrophs but also forms the base of the food chain for heterotrophs. Additionally, the oxygen released during photosynthesis contributes to atmospheric oxygen levels, essential for respiration in animals and humans. Understanding photosynthesis is crucial for addressing climate change, as it directly influences the levels of atmospheric CO2.
