carbon dioxide

n.
A colorless, odorless, incombustible gas, CO2, that is formed during respiration, combustion, and organic decomposition, is an essential component in photosynthesis, and is used in food refrigeration, carbonated beverages, inert atmospheres, fire extinguishers, and aerosols. Also called carbonic acid gas.

carbon dioxide

A colorless, odorless gas, CO2, that is present in the atmosphere and is formed when any fuel containing carbon is burned. It is breathed out of an animal's lungs during respiration, produced by the decay of organic matter, and used by plants in photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks.

carbon dioxide

A gas in air. In the carbon cycle, plants make food with carbon dioxide, and breathing, burning, and decay return it to the air. See greenhouse gases.
