Answer 1

It will become poisonous and kill living forms

Explanation:

Oxygen is found in the atmosphere in two forms, i.e., as diatomic molecule (O₂) and as ozone (O₃). Ozone exists as a thick blanket called ozone shield or ozonosphere in the stratosphere. Unlike diatomic oxygen, ozone is poisonous. When inhaled, ozone can damage the lungs, and cause other respiratory diseases like asthma etc. Ozone is a weak mutagen and produces various chromosomal abnormalities. So, if all oxygen present in the environment gets converted into ozone, then air will become toxic and kill all living forms.
