Name three important needs for water.

Among the three needs for water are:

1. Biochemical mechanisms including digestion, photosynthesis and cellular respiration.

2. Habitat for many species of animals, plants and microorganisms.

3. Most abundant substance in living organisms.

Explanation:

Water is a substance that is generally in a liquid, gaseous and solid-state, but it is the liquid state that is the most important for life. It represents approximately 71% of the earth's surface and is a vital substance for the planet and living beings.

Water is essential for the maintenance of ecosystems and the habitat of all species of animals, plants, and microorganisms because every living being is composed and needs water to a greater or lesser extent to live.

Water also plays a vital role in the biochemical mechanisms of living beings. For example, cellular respiration is an essential process for cellular nutrition. Through this process, the cells receive oxygen from the environment to produce energy and water. Therefore, water is vital in different methods that are essential for life on the planet.

I hope this information can help you.

Important needs of water;

1. It is an important habitat for some living organisms.

2. It is important for photosynthesis, cellular digestion and respiration.

3. It use for cycling materials that the living organisms uses.

Explanation:

Water is a universal solvent that is tasteless, odourless and colourless. It is an inorganic solvent essential for life. It contain oxygen and hydrogen elements and also exist in three forms, liquid, gaseous and solid. It is important for cellular respiration and photosynthesis.
