Why is the hydrosphere important?
The hydrosphere is important because it is all the water on the earth's surface, and living organisms need water to survive. Organisms are made up of 75% of water, and it allows the cell to function normally. Without water, life would not exist, because most of the cell's functions deal with water.
Plants and Animal Life
Anything of aquatic species such as dolphins, seaweed, and plankton live in the hydrosphere.
