Why do fish die when taken out of the water??????????????????????
Fish takes the dissolved oxygen from the water for respiration. As you know fish does respiration through its gills. The gill tissues allow the water to move in between the gill membrane and oxygen can diffuse into fish’s blood stream. So, there must be a constant flow of water over gills. If the fish are taken out of water, it suffocates and dies because of little oxygen. Without water, the gills dry and stick to each other, and gas exchange cannot take place.
