Water is a fundamental necessity for all living organisms as it plays a crucial role in biological, physiological, and ecological processes.
- Essential for Cellular Functions – Water is a key component of cells and tissues, helping in various biochemical reactions, including digestion, respiration, and nutrient transport.
- Medium for Biological Reactions – Most metabolic activities occur in a water-based environment, ensuring proper functioning of cells.
- Regulation of Body Temperature – In humans and animals, sweating and evaporation help regulate body temperature.
- Transport of Nutrients and Waste – Water helps in dissolving and carrying nutrients to cells and removing waste products through excretion.
