Question

what is the importance of carbon dioxide and oxygen for living beings​

Answer 1

Explanation:

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.

Answer 2

All living things need some of the gases in air for life support. In particular, all organisms rely on oxygen for respiration—even plants require oxygen to stay alive at night or when the Sun is obscured. Plants also require carbon dioxide in the air for photosynthesis.
