Explanation:
Organisms in 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 nitrogen wastes and other substances such as hormones that would be toxic if allowed to accumulate in the blood) through organs ...
Answer:
Aquatic organisms have higher concentration of water outside their bodies, which causes endo–osmosis. Osmoregulation i.e., the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
Osmoregulation is the active regulation of the osmotic pressure of an organism 's fluids to maintain the homeostasis 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 on the hypertonic side of a selectively permeable membrane to prevent diffusion 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.
