Hello candidate,

Carbon forms a very important and the most essential element for all life existing on the planet, as the basic constituents of life including the muscles, cells, and tissues highly composed of carbon.

The global carbon cycle is represented as the distribution of carbon among the four prominent spheres such as fossil fuels, atmosphere, oceans, and land. The carbon cycle signifies the presence of life in a cyclic way, and its distribution among the major reservoirs.

Hope this information helps you!!
