Carbon dioxide (CO2) and oxygen (O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis, in which plants use CO2 and water to convert the Sun's energy into food energy. This food energy is in the form of the sugar glucose (C6H12O6). Plants also produce O2.
