Oxygen in the atmosphere is important for life for two main reasons. First, oxygen makes up the ozone layer. The ozone layer is in the upper part of the atmosphere, and is mad â¦ e of O3 molecules-a particular type of oxygen molecule. It blocks harmful radiation from the sun and keeps it from reaching Earth's surface.xygen (in the form of O2) is needed for almost all life because it is used in the process of cellular respiration in which cells react oxygen with glucose to form water carbo â¦ n dioxide and heat.
