[OU.03] A star is an example of a blackbody radiator because

A star is an example of a black body radiator because  it reflects most of the light falling on them.  It can neither emit nor absorb all wavelengths of light . Its spectrum shifts to short wavelengths as temperature increases. Its wavelength peaks in the blue end of the spectrum as temperature decreases.

Explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
