Carbon cycle:- carbon is the most abundant element as it occurs in every organic substance. It forms 49% of the dry weight of organic matter. There are three types of fossil fuels Coal, Petroleum and natural gas.
Circulation:-
1) addition:- carbon dioxide is being added to the cycling pool of atmosphere and Hydrosphere through two processes biological and non biological.
Biological:- all living organisms produce carbon dioxide through respiration.
Non biological:-
combustion of biomass and fossil fuels produce carbon dioxide.
2) utilisation:- carbon is taken out of cycling pool of both atmosphere and Hydrosphere by all photosynthetic organisms or producers. The amount is 4 × 10¹³ kg per year. It is changed into organic matter through photosynthesis.
