MCQ
Biological importance of Ozone layer is
  • It stops ultraviolet rays
  • B
    Ozone rays reduce green house effect
  • C
    Ozone layer reflects radio waves
  • D
    Ozone layer controls ${O_2}/{H_2}$ radio in atmosphere

Answer

Correct option: A.
It stops ultraviolet rays
a
Ozone is $O_{3}$ present in stratosphere region of the atmosphere, which protects us by absorbing harmful Ultraviolet radiation released by the sun that causes a variety of health problems in humans, plants, and other animals which leads to the damage in ecosystems. Plants do not and grow in heavy ultraviolet radiation.

Hence option $A$ is correct.
