Which layer helps protect living organisms because of ozone?
Answer and explanation
Correct answer: Stratosphere
The ozone layer is concentrated mainly in the stratosphere, so option D is correct. Ozone absorbs much of the Sun’s harmful ultraviolet radiation, reducing damage to living cells and ecosystems at Earth’s surface. The troposphere contains most weather, while the mesosphere and exosphere are not the main protective ozone region. Thus the key link is stratosphere–ozone–UV protection.
