State the importance of the solubility of CO2 and O2 in water.
The concentration of two of these is particularly important. The concentration of oxygen in water is crucial to aquatic animals that depend on dissolved oxygen for respiration.
However, the oceans are no longer able to absorb the increased concentration of carbon dioxide in the atmosphere without changes to acidity levels.
CO2 and O2 is important for the aquatic animals. CO2 for aquatic plants and O2 for aquatic animals.
