Explain how osmosis contributes to organisms that are not isotonic
?Most simple marine organisms have nearly the same concentration of dissolved substances in their body fluids as seawater does. They are almost isotonic to their fluid environment and experience little net flow of water through their outer membranes. In freshwater, a marine animal would be hypertonic to its surroundings; water would move into the animal through its cell membranes. If the animal had no way to eliminate the water, its cells would burst. The same kind of marine animal moved to Utah's highly saline Great Salt Lake would be hypotonic, and would flow out of its cells, causing it to dehydrate and collapse.
