Describe the usefulness of water in biosphere and biological systems ?

Hi student
For all forms of life on earth, water is very much essential.it is one of the most unique molecule known to man.Not only does water exist in nature in all three states of matter (solid, liquid, gas), it also covers 75 percent of the earth and composes roughly 78 percent of the human body.
The high heat of vapourization and heat of capacity of water helps in moderating the climate and body temperature of all living beings.
It acts as a carrier of various nutrients required by plants and animals for various metabolic reactions.Earth surface waters are filled with life. The earliest life forms appeared in water; nearly all fish live exclusively in water
Water plays an important role in the biosphere since it has high specific heat, thermal conductivity, surface tension, dipole moment, and dielectric constant.The high heat of vapourization and heat of capacity of water helps in moderating the climate and body temperature of all living beings.
