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.
icrod is right...it is because the fish can only take in dissolved oxygen from the water in which they live in. that is why fish cant take in the pure and undissoled oxygen and die when taken out of water because then they have no supply of oxygen in them.
@icrod that answer was perfect.......keep it up
Every animal, humans,insects,fishes.etc have different type of organs for breathing.Human beings which is us, breathe through lungs, such in this way fishes have different organs for breathing called Gills.We cannot breathe underwater wheras the fish cannot breathe outside water because They Breathe Underwater.This is the reason why fish die if taken out of water.
