Answer 1

Answer:

The ozone layer or ozone shield is a region of Earth's stratosphere and is essential in sustaining life on Earth. It acts as a shield for life on Earth because it is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms' protective layers, like skin, damaging DNA molecules in plants and animals.
