Why salt water fish thrown in pure water will burst and get killed?


 

Why salt water fish thrown in pure water will burst and get killed?

 

When the fish live in salt water , the cells of the fish accustomed to maintain high concentration. But when the fish is thrown in fresh water,   hypotonic condition exists outside the fish.  Due to this difference in concentration, through endosmosis water from outside enters into the cells of the fish. As the cells of fish absorb more and water through endosmosis, the cells become very much swollen and burst. Thus the fish will be killed.
