Oxygen is an element that is found in the atmosphere and is necessary for many forms of life to survive. It is the most abundant element in the atmosphere and makes up about 21 percent of the air. Oxygen is used by all living things to produce energy. During the process of respiration, oxygen is taken in by cells and combined with other molecules to produce energy. Oxygen is also used in many industrial processes, such as welding and combustion, and is used to produce electricity in fuel cells. Oxygen can also be used to purify water and is used in medical treatments such as oxygen therapy.
