The carbon cycle is the process in which carbon atoms are recycled over and over again on Earth . Carbon recycling takes place within Earth s biosphere and between living things and the nonliving environment . Since a continual supply of carbon is essential for all living organisms , the carbon cycle is the name given to the different processes that move carbon from one to another .
The complete cycle is made up of sources that put carbon back into the environment and sinks that , absorb and store carbon .
Carbon cycle is the transfer of CO2 molecules from one phase to another in a manner . All living things are made of carbon . Carbon is also a part of the ocean , air and even rocks .Because the Earth is a dynamic place , carbon does not stay still.If we see from beginning CO2 in the atmosphere is taken by the plants which use it to make glucose , water and oxygen .Also direct CO2 from air forms carbonate water which later turns to Limestone . Then these plants are eaten by us and other animals i.e we indirectly use the CO2 which was with plants and also we respire CO2 back in atmosphere. Then , when organic compounds [plants, animals] form coal and petroleum or we can say fossil fuel , additionally our human body forms inorganic carbonate or shells .But nowadays we burn fossil too much which is harmful and also cutting the trees as a result we are not getting rid of CO2 from our atmosphere .
