CO2 fixation

CO2 fixation is the process by which plants, algae, and certain bacteria capture carbon dioxide from the air and convert it into organic molecules, mainly sugars. Using energy from sunlight through a process called photosynthesis, they attach CO2 to other molecules like ribulose bisphosphate, forming new compounds that serve as the basis for growth. This process removes CO2 from the atmosphere and stores it in organic matter, playing a crucial role in maintaining Earth's carbon balance and supporting life by providing the fundamental building blocks for all living organisms.
