Oxygen is essential for the survival of most living organisms on Earth, as it plays a critical role in cellular respiration, the process by which cells produce energy. This energy is necessary for various biological functions, including growth, repair, and maintenance of bodily systems. Additionally, oxygen is vital for the formation of ozone in the atmosphere, which protects life on Earth by filtering harmful ultraviolet radiation from the sun. Without oxygen, ecosystems would collapse, and life as we know it would not exist.
