Answer:
The carbon cycle operates in nature that maintains the carbon composition in nature. The carbon is released into the atmosphere in the form of oxides, hydroxides and then recycle back into the atmosphere.
The carbon can be released into the atmosphere by the respiration of the animals in the form of carbon dioxide. The burning of fossil fuels and wood combustion also releases carbon into the atmosphere. The decomposition by microbial organisms also releases carbon dioxide in the nature. The main carbon reservoir present in the atmosphere is lime stones in the oceans and in the biomass of the organisms. The carbon can be used up by the plants during the process of photosynthesis.
