Q

How is water imporant for aquatic life

A

Water has thermal stability so it is a stable environment for aquatic animals
Its a liquid between 0-100 degrees so it can be used to transport medium for aquatic plants and animals
Ice has a lower density so it floats on top of water, insulating the water before
Water is transparent so light can be passed through for plants
Small animals are able to move across the surface of the water due to its surface tension
