Carbon dioxide (chemical formula: CO2) is a chemical substance that occupies about 96 % of Mars's atmosphere.
Biological significance
The metabolism of human beings, animals and various microbes depends on the oxidation of carbohydrates, resulting in carbon dioxide exhalation.
Plants use the carbon from CO2, and release the oxygen back to the atmosphere.
Uses
Carbon dioxide can be used to produce
- Oxygen in greenhouses by plants
- Synthetic materials
