Oxygen is a colorless, odorless, and tasteless gas that is essential for human life. It makes up approximately 21% of the Earth's atmosphere and is a critical component of the air we breathe. Oxygen is also a key element in the process of cellular respiration, where it is used to generate energy for the body.
