Answer:
"Hydrosphere provides a place for many plants and animals to live in. Many gasses like CO2, O2, nutrients like ammonium and nitrite(NO–2) as well as other ions are dissolved in water. The presence of these substances is essential for life to exist in water."

˙❥˙Hydrosphere is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite. ... Moreover, water is essential for the survival of life, or in short, for life to exist.
▶ It is said to play an important role in regulating the climate.
❥˙The major importance of the hydrosphere is that water sustains various life forms and plays an important role in ecosystems and regulating the atmosphere.
☞It involves saltwater, freshwater, and frozen water along with groundwater and water in the lower levels of the atmosphere.
1. One of the basic needs of human
Apart from drinking, water is essential for cooking, cleaning, washing and even for the functioning of so many industries. In addition to this, water is necessary for agriculture and the generation of electricity through hydropower. It is difficult to imagine a day without water.
2. Part of living cell
The main component in the cells of all living organisms is water. It is found that 75% of the cell is composed of water. Most of the chemical reactions occurring in the cells are mainly due to the presence of water. Survival of a cell is impossible without water. In plants, the energy transportation is done with the help of these water molecules only.
3. Habitat for many organisms
Hydrosphere is the habitat for numerous aquatic plants and animals. The number of living organisms in water is high when compared to the number of organisms that are living on land. Plants and animals in the water make use of gases such as oxygen and carbon dioxide that are dissolved in water for their existence. They also use nutrients such as ammonium ions, nitrate, etc. for their life.
4. Regulates temperature
One of the important features of hydrosphere is that it helps to regulate the temperature of the environment. The specific heat capacity of water is the main property by which this regulation is happening. Water takes time to heat as well as to cool. So the places surrounded by water bodies like oceans and lakes tend to have a balanced climate. The temperature in the coastal areas may not have extremes of temperature differences. Not only maintains atmosphere temperature, but also regulates temperature all living organisms.
5. Atmosphere existence
Hydrosphere plays an important role in the present form of atmosphere. Above 400 million years ago, the earth’s atmosphere was covered with helium and hydrogen. Earth’s atmosphere was very thin and was similar to the planet Mercury’s present atmosphere and the temperature was around 600°C. Later on, when the earth surface cooled and as a result of so many chemical reactions, the water bodies and atmosphere formed in massive.
