Water is the major constitutent of living matter. From 50 to 90 percent of the weight of living organisms is water. Protoplasm, the basic material of living cells, consists of a solution in water of fats, carbohydrates, proteins, salts, and similar chemicals. Water acts as a solvent, transporting, combining, and chemically breaking down these substances. Blood in animals and sap in plants consist largely of water and serve to transport food and remove waste material. Water also plays a key role in the metabolic breakdown of such essential molecules as proteins and carbohydrates. This process, called hydrolysis, goes on continually in living cells.|
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.
