Question

Quizplus · Accepted Answer

Marine bony fishes are surrounded by a hypertonic environment, meaning that they have a higher concentration of water in their bodies than their surroundings. Therefore, they lose water by osmosis, which is the passive movement of water from an area of high concentration (the fish's body) to an area of low concentration (the surrounding environment). Terrestrial animals, on the other hand, lose water through evaporation, which occurs through their skin and respiratory system. They may also lose water through urine and feces, which is not an option listed in the choices. Active transport and simple diffusion are not involved in the loss of water in either marine bony fishes or terrestrial animals.
