Ozone present in the ozone layer of the atmosphere is important because

فضا کی اوزون تہہ میں موجود اوزون کس لیے اہم ہے۔

It shields other gases

It helps in the growth of the plants by absorbing a large proportion of the sun's ultraviolet radiations

It gives oxygen on dissociation

None of these

Ozone protects the Earth from harmful ultraviolet (UV) rays from the solar. with out the Ozone layer inside the atmosphere, existence on the earth could be very hard. plant life cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the sea existence.
With a weakening of the Ozone Layer defend, human beings would be greater at risk of skin cancer, cataracts and impaired immune systems.
Ozone can both shield and damage the Earth — it all depends on in which it is living. for example, if Ozone is present in the stratosphere of the ecosystem, it's going to act as a guard.
however, if it is in the troposphere (about 10 km from the Earth's floor), Ozone is harmful. it's miles a pollutant that could purpose damage to lung tissues and plants. hence, an upset inside the ozone balance can have extreme outcomes
