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.
