Question

Why is osmoregulation necessary in aquatic organisms?​

Answer 1

Answer:

Osmoregulation is the active regulation of the osmotic pressure of an organism 's fluids to maintain thehomeostasis of the organism 's water content; that is it keeps the organism 's fluids from becoming too diluted or too concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution the more water wants to move into the solution. Pressure must be exerted onthe hypertonic side of a selectively permeable membrane to preventdiffusion of water by osmosis from the side containing pure water.

Organisms in both aquatic and terrestrial environments must maintain the right concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic wastes and other substances such as hormones that would be toxic if allowed to accumulate in the blood) via organs such as the skin and thekidneys; keeping the amount of water and dissolved solutes in balance is referred to as osmoregulation.

Answer 2

They must also develop mechanisms to prevent the loss of solutes as excess water is excreted. The process by which organisms actively maintain their internal solute concentration is called osmoregulation. ...

Importance: The work required for osmoregulation depends on properties of the organism and its environment.
