Question

how is aquatic life benefitted by the fact that water has maximum density at 4°c.
​

Answer 1

When cooled from room temperature, liquid water becomes dense but at 40Cpure water reaches its maximum density. As it is cooled it expands to become less dense. So the layer of ice floats on water as insulating layer. The warm layer settles at the bottom in winters and so aquatic life exists.
