What is the source of carbon?

Answer 1

Carbon is a naturally occurring element on the earth. It is the "magic" chemical element that is the building block of all life we know. Carbon was made in stars during their lives when they fused lighter elements into heavier ones (stellar nucleosynthesis).

Animal cells give off carbon in the form of CO2 (carbon dioxide) or in waste materials.

Answer 2

Carbon is formed in the cores of certain stars after lighter elements have been formed. The carbon on earth came from older stars that exploded to release their carbon.

On Earth, carbon is found as carbonate rocks, and dissolved in seawater as carbonic acid, and in the air as carbon dioxide. Plants and animals contain a small fraction of the Earth's total carbon.

Answer 3

carbon dioxide is usually released from combustion, or any sort of burning. when a fire consumes the right material, as an example wood, the carbon in the material that is burning gets bonded with the oxygen molecules in the air the fire is using. two carbon atoms from the burning material plus a oxygen atom from the surrounding of the fire equals an molecule of carbon dioxide, which is the smoke you see from a fire.

however, sometimes when the fire does not have enough oxygen atoms around itself to sustain a proper combustion, carbon monoxide, the evil brother of carbon dioxide, is formed by the partial burning of a material. it only has one carbon atom and can kill you in a matter of seconds, minutes, pron to exposure to it

Answer 4

carbon can be made in a star through a process called fusion, its what happens when a star uses up all of its hydrogen, fuses helium,fuses other elements and eventually gets to carbon, then a star keeps fusing elements on the Periodic Table until it reaches iron then it can turn to a black hole,super nova or a nebula

Answer 5

The source of carbon for animals if food.

Answer 6

probably trees....
