Explain carbon cycle in nature with suitable flow chart.

Explanation

The main sown o of cotton in this universe is `CO_2`, which is dissolved in water and present in the air (0.03 to 0.04%).
(II) Plants take up carbon-dioxide from . atmosphere and form organic compounds during photosynthesis. These organic compounds are transferred to animals as their food.
(iii) The carbon-dioxide is returned back to the atmosphere during respiration, decay and combustion of plants and animals.
(iv) The organic compounds of FOSSIL FUELS plants and animals are buried in the deep soil where they are act by decomposers to change them in petroleum, coal, oil and carbonate roc.. These substances on their combustion release `CO_2` , into atmosphere.
(v) Some `CO_2`, is found in dissolved state in HO. This gets convened into `CaCO_3`, in lime stone. The weathering and combustion of carbonates containing rocks or treatment of their minerals gives `CO_2`
(vi) The hot springs and volcanic eruptions also given out `CO_2` into the atmosphere
