✓

Answer

Osmoregulation: For the successful functioning of all biological activities of living beings, concentration of water and essential salts in a certain range in their body or bodily fluids is necessary. This helps in maintaining the desired osmotic pressure in their body fluid. Different aquatic organisms live in aquatic habitats with different osmotic properties and according to the nature of the habitat, they regulate the osmotic pressure and certain concentration of salts in their body fluids through various mechanisms. This regulation by living organisms of the amount of water and salts in their bodies is called osmotic regulation.
