WATER CONSERVATION

Water is essential for life. It is required to exchange gases (e.g., oxygen and carbon dioxide) in respiration, it transports nutrients through the body, it is involved in most metabolic processes, it dilutes and removes wastes, and it serves as a coolant. Water is acquired by animals through drinking (free water), through water in their food (preformed water), and through water produced as a by-product of metabolizing food (metabolic water, see respiration). Water is acquired by plants from the soil using their roots.

Water is lost by plants and animals by three avenues:

Some of the ways to reduce water lost by the three avenues are given below. Torpor reduces water lost by all three avenues also.
