9.28 Describe the usefulness of water in biosphere and biological systems.
Water is essential for all living beings. It plays an important role in the biosphere. its has high specific heat, thermal conductivity, surface tension, dipole moment, and dielectric constant.
The high heat of vaporisation and heat capacity are responsible for the moderation of the climate and body temperature of living beings. It is an excellent solvent for transportation of ions and molecules required for plant and animal metabolism.
