Biological importance of Ozone layer is : -The ozone layer in the stratosphere absorbs most of the harmful ultraviolet radiation (especially UV-B) coming from the sun.
UV radiation damages DNA and proteins, causing skin cancer, cataract and damage to plants and plankton.
So the ozone layer acts as a protective shield for life on earth.
It does not reflect radio waves (the ionosphere does) or reduce the greenhouse effect.
So its biological importance is that it stops ultraviolet rays.
