Answer 2

Inspite of the large amount of carbon dioxide entering the atmosphere due to breathing and combustion, there is a mere fraction of CO2 available in the atmosphere.

This is possibly due to two reasons:

* Green plants convert most of the carbon dioxide into glucose in the presence of sunlight

* Carbonates get dissolved in sea water which marine animals use to form their shells
