Some of the rain that has fallen back down to the earth flows into the streams and then carfied into the sea. The water that did not flow into the streams to be carried back into the oceans goes into the soil where the plants can take it up. Some of the water that seeps into the soil goes farther into the earth and joins the ground water. After all this happens the cycle begins again and keeps on going through. Water is very important to living organisms.
Water helps cells to keep their form.
Water as a solvent dissolves salts, sugars, proteins, and many other substances that are used in the process of metabolism and the digestion of food. Water also allows the transportation of bodily wastes, and the support of a stable body temperature through perspiration and evaporation. Although water is very helpful and has hardly any dangerous effects, too much water can be dangerous. One way organisms gain water is through food, and by respiration. Organisms lose water thmugh evaporation, urinating, and by osmosis.
