During winter, water bodies freezes
is an incomplete statement. Then what is right? Let's see...
- As the top
layer of water bodies comes in contact with outer environment so,
only outer layer of water bodies get freezed but the water below
this freezed layer remains in liquid form with low tempreature. The
thickness of frozen layer depend on the outer environment
tempreature. Below this frozen layer the presence of water leads to
the aquatic life ongoing.
- There may be
another aspect, and that is little change in hydrostatic pressure
of the environment (below the frozen layer) in which aquatic
animals are living in winter. But we all know that every animal
have ability to adopt within the permissible (bearable) change in
the surrounding. The basic need for an aquatic life is the presence
of water so that they can get the required food and oxygen.
Thankyou
