Respiration:
In this step, animals take oxygen and in turn, release carbon dioxide in the atmosphere. This process continuously moves in repeating manner.
Formation of Ozone
Oxygen and its products are present in the atmosphere. Ozone is an important product of oxygen.
In stratosphere, ozone layer plays a preventive role.
Dangerous ultraviolet rays are prevented to reach at earth by ozone layer because ultra violet rays are very harmful for animals, plants, and whole part of earth.
Ozone Layer in the Atmosphere
Ozone is a secondary pollutant if it is produced in troposphere than stratosphere.
Accelerates/supports combustion, major hurdle in fire-fighting. But choking the fire of oxygen supply extinguishes the fire. Reacts with almost all the metals to form oxides and bring about corrosion.
Generally known as rusting in the context of iron. Humans breathe oxygen, but if we try to inhale pure oxygen. It could prove harmful to our internal organs. This is because of oxidizing nature of oxygen. Animals and plants survive due to presence of oxygen into different segment of environment.
