Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. In cold countries, in winter, a layer of ice is formed on the surface of lakes when the atmospheric temperature falls below 0°C.

2. However, below this layer, there is water at 4°C.

3. Ice, being a bad conductor of heat, does not allow transfer of heat from this water to the atmosphere.

Hence, aquatic animals and plants can survive in this water.

Hope it helps!
