Why is water very precious for all living beings?

Hint: The total amount of water which is present on the earth is not suitable for drinking purposes. Water which is useful for drinking purposes is called potable water. Water should contain certain parameters for drinking purposes.

Complete step by step solution:
- In the question it is asked why water is very precious to all living beings.
- The reason behind is that life began in the oceans, and no living being cannot survive without water.
- That means no living thing can survive without water then water is called a source of life.
- In all living organisms the major part is occupied by the water.
- Human body (nothing but blood) consists of 90 % water.
- The more advantageous property of the water is it has a capability to dissolve the large number of compounds in it.
- In industries also water is used as a solvent to do so many chemical reactions.
- The aquatic animals also survive in water in large amounts in the form of oxygen reservoirs.
- One more important thing is that a large number of fruits contain the maximum amount of water in them.
- That is the reason why water is very precious like oxygen from living beings.

Note: Water and oxygen are the two things that make the survival of the huge amount of living beings in the earth. We cannot imagine the earth without water and oxygen. These two compounds or chemicals are ruling the earth directly.
