Oxygen dissolves in surface water due to the aerating action of winds. Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis. When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive. ... As the water becomes warmer, less oxygen can be dissolved in the water.

Does oxygen dissolve in water Yes or no?

Although the concentration of oxygen in the air is quite high, O2 is not very soluble in water. At a pressure of one atmosphere (atm) of air, the oxygen concentration in water at room temperature is about 8.2 mg/L or 8.2 parts per million (ppm) at saturation level. ... They are also affected by water released from dams.
