Answer Details
When a marine fish is taken from the ocean and put in a tank of fresh water, it dies after a short period because the body cells of the fish swell and burst as a result of the hypotonic fresh water. The cells of the fish are adapted to a high concentration of saltwater, and when they are placed in freshwater, which has a lower salt concentration, water moves into the cells of the fish through osmosis. This causes the cells to swell and burst, leading to the death of the fish.
