In aquatic animals

Quizplus · Accepted Answer

Aquatic animals primarily gain or lose water through osmosis, which is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. Solutes are gained or lost by passive diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration across the body surface. This process does not require energy and is fundamental to how aquatic animals regulate their internal environments.
