carbon dioxide :p
A molecule is the fundamental unit of a compound. Therefore, a molecule of carbon dioxide is one C and two O atoms bonded together. A molecule is a single unit whereas a mole is a group of molecules and represents a fixed no. of any substance. Therefore, one mole of Carbon Dioxide consists of a 6.022 x 1023 molecules
It is not fixed in the atmosphere. It moves as part of the carbon cycle in and out of the oceans, the atmosphere and the land.

carbon dioxide is used in the Calvin cycle.

The carbon and oxygen atoms in carbon dioxide are strongly attracted to each other, and carbon dioxide in the air will only break up into separate carbon and oxygen atoms at very high temperatures, higher than the temperatures usually found in nature on earth. In green plants, however, a chemical called chlorophyll in the cells of the plants can use the energy of light (usually sunlight) to break apart the carbon dioxide into carbon and oxygen, even at ordinary temperatures. The oxygen is released into the air, and the carbon is combined with other elements to create sugars, starches, cellulose, and other organic compounds that become part of the plant.

Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s.
carbon fixed in photosynthesis
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.
