Why do fishes die when taken out of water?

टिप्पणी लिखिए

उत्तर

Fish do not have lungs that can utilise the oxygen of the air for breathing and respiration. The fish have gills. Gills can only extract the dissolved oxygen from water and provide it to the fish. Gills cannot take in the oxygen from the air. Since fish do not get oxygen for breathing when taken out of water, they die.
