Ozone protects biosphere from ______
Ultraviolet rays
The ozone layer in Earth's stratosphere absorbs and scatters harmful ultraviolet (UV) radiation from the sun (option 3), particularly UV-B and UV-C rays. This protection is crucial for preventing DNA damage in living organisms, reducing skin cancer risks, and maintaining ecosystem balance. Ozone depletion allows more UV radiation to reach the surface, posing serious environmental and health risks.
