Question

What happen if you keep freshwater fishin sea water and why?

Answer 1

If fresh water fish is kept in sea water, it will be exposed to highly concentrated water.So water tends to move out of the fish.Fish will get dehydrated and may die. This is due to osmosis.Water always moves from dilute solution to concentrated solution.Fish body is dilute here and out side water is concentated.So water will move from fish body to sea water.
