How do aquatic animals manage to live in Arctic and Antarctic Circle?
Advertisements
उत्तर
In the Arctic and Antarctic circles, water in lakes and ponds will be frozen and a solid layer of ice is formed on the surface of the water. Still, aquatic animals living under the ice do not die. This is because the floating layer of ice acts as a protective coat and does not permit heat to escape from the water. So as the surface water alone turns to ice, the aquatic animals manage it.
