Importance of water of living organisms speech
Answers
Living organisms need water to survive. Many scientists even believe that if any extra-terrestrial exists, water must be present in their environments. All oxygen-dependent organisms need water to aid in the respiration process. Some organisms, such as fish, can only breathe in water. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.

Water is one of the most important resources on the planet. Without water, life cannot exist. But what makes water so important? Water has several unique characteristics that make it an extremely valuable resource. Some such properties of water are listed below.
️️
- Water is a very good solvent – it has the ability to dissolve many substances.
- The boiling point and freezing point of water make it easily available in all three states (solid, liquid, and gaseous).
- The specific heat of water is quite high. This enables water to absorb and release heat slowly, thereby regulating the temperature of its environment.
- Owing to its transparency, water can allow light to reach the life forms that are submerged in it. This is crucial for the survival of plant life in the oceans, lakes, and rivers.
- Water is neither acidic nor basic in nature. It has a pH of 7, making it a neutral substance.

These unique qualities of water, along with its abundance on the planet (approximately 71% of the Earth’s surface is made up of water), make it a crucial resource for plants, animals, and human beings.
