What gas in the atmosphere important to respiration?
The essential gas is oxygen...
Why is O2 essential to life?
Another critical gas is oxygen gas (O2). Much of life on this planet is aerobic, meaning oxygen is required for survival. Oxygen serves as a key constituent in the process that releases the energy stored in food.Oxygen is not essential to all life. In fact there are some organisms that die in the presence of oxygen. There was once a time when there was no oxygen in our atmosphere and only anaerobic organisms lived. Water is essential to all known life but not oxygen.
