The effect(s) of ozone depletion include(s)(a) inhibition of photosynthesis in phytoplanktons(b) damage in nucleic acids of living organisms(c) increase in UV-radiations reaching the earth surface(d) All of the above

Answer»

Answer is : (d)

The depletion of ozone layer leads to an increase in ground level ultraviolet radiation, because ozone is an effective absorber of ultraviolet radiation. The effects of ozone depletion include inhibition of photosynthesis in phytoplanktons which affects the food chains. It damages nucleic acids in living organisms (mutation). The ozone depletion causes an increase in UV radiations reaching the earth’ surface which can cause skin cancer.
