Question

how aquatic life is possible under ice ?

Answer 1

due to anomolus expansion of water water at the gruond level is maintained to 4 degree celcius

Answer 2

..Due to anamolous expansion of water....
Only the top layer of a lake or river freezes, un- derneath the frozen upper layer the water remains in its liquid form and does not freeze. .....
Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. ........
The surface water finally freezs while the lower layer remain at 4c as ice is a bad conductor of heat freezing in the lower layer is a very slow pprocess. Thus underneath the frozen layer
fish and other aquatic animals and plants survive. ......☺️☺️☺️
