Answer
Biological importance of carbon dioxide dissolved in water :
- Aquatic plants make use of dissolved carbon dioxide for photosynthesis, i.e., to prepare their food.
6CO2 + 12H2O C6H12O6 + 6O2 + 6H2O - Carbon dioxide dissolved in water reacts with limestone to form calcium bicarbonate.
CaCO3 + CO2 + H2O ⟶ Ca(HCO3)2
Marine organisms such as snails, oysters, etc., extract calcium carbonate from calcium bicarbonate to build their shells.
