Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.
Further Explanation:
In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.
CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.
Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

Answer:
The definition of an organism is a creature such as a plant, animal or a single-celled life form, or something that has interdependent parts and that is being compared to a living creature. An example of an organism is a dog, person or bacteria. An example of an organism is one party in the political organism.Types of Organisms. Scientists classify organisms into 3 domains and 6 kingdoms, although this has changed throughout history. There are 3 recognized domains, or broadest classification of organism. These are Bacteria, Archaea, and Eukarya.
Explanation:
For young students things are 'living' if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move. Others think plants and certain animals are non-living.You need a microscope to see them. They are called microorganisms. Organisms can be made up of just one cell. They are called unicellular organisms or single celled organisms. Examples include bacteria, and protozoa such as the Amoeba and Paramecium.
