The Earth's atmosphere is composed of approximately 21% oxygen. This oxygen is essential for the respiration of most living organisms and plays a crucial role in various biochemical processes. The majority of the atmosphere is made up of nitrogen, which accounts for about 78%. Other gases, including carbon dioxide and trace gases, make up the remaining percentage.
