Water is useful to us and nature in many ways. They provide a home for creatures such as the whale, otter, etc. These sea-creatures depend on the water to live. The whale can't be out of the water for long before it dies. The sea-otter live on the shell-fish and fish that live in the water. Ducks eat the sea-weed that live in the water and some also eat fish. Lots of what these animals eat also live in the water. As you know, water has three states, liquid, gas, and solid. The solid state of water is ice. Ice is also a habibtat. Penguins, seals, and other types of animals live on huge pieces of ice. Many penguin species live on Antarctica and the North Pole. Seals also live on these pieces of ice. Not all of the are permanent homes. A seal might just want to stop by at a glacier and rest.
One thing important to us is hydroelectric power. Hydroelectric power is power derived from the fall of water from a higher to a lower level, and extracted by means of waterwheels or hydroelectric turbines. Read more about this in hydroelectric power. Waterpower is a natural resource, available wherever a sufficient volume of steady water flow exists. Water is something vital for our survival. It is the major constitutent of living matter. From about 50 to 90 percent of the weight of living organisms is completely water. Protoplasm, the basic material of living cells, consists of a solution in water of fats, carbohydrates, proteins, salts, and other similar chemicals. Water acts as a solvent, transporting, combining, and it also chemically breaks down these substances. Blood in animals and sap in plants consist largely of water and what it does is that it transports food and removes waste material. Water also plays a key role in the metabolic breakdown of some molecules as proteins and carbohydrates. This process is called hydrolysis and it goes on continually in living cells.
