What is Carbon Fixation?

Carbon fixation is a crucial biological and chemical process where carbon dioxide (CO₂) from the atmosphere is converted into organic compounds.

The process forms the foundation of the carbon cycle. It plays an important role in sustaining life on Earth and regulating its climate.

Essential for All Life on Earth

• Carbon fixation is essential for all life forms on Earth as it provides the primary organic carbon source.
• Plants, algae, and certain bacteria perform photosynthesis to fix carbon and convert atmospheric CO₂ into carbohydrates and other organic compounds. 
• Herbivores and omnivores consume plants and pass on fixed carbon through the food chain. Carnivores then obtain fixed carbon by consuming herbivores or other carnivores.
• Carbon fixation creates the organic molecules that constitute all living organisms’ cells, tissues, and structures.
