Oxygen is continuously replenished in Earth's atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.
Oxygen is one of the most important elements as it is needed by most forms of life to survive on Earth. Oxygen is represented by the Symbol O and Atomic Number 8, is a member of the Chalcogen Group.
Jun 25, 2024 · Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.
Oxygen is a life-saving essential medicine with no substitution. Healthcare professionals use oxygen to treat respiratory illnesses like COVID-19 and pneumonia. Oxygen is also essential for surgery and trauma. Vulnerable groups like older people, pregnant women, young infants and newborns need oxygen therapy regularly.
