What is ozone and how does it affect any ecosystem?
What is ozone and how does it affect any ecosystem?
solution:
(i) Ozone is formed in atmosphere by the action of ultraviolet radiation on oxygen gas.
(ii) The high energy ultraviolet radiation (UV radiation) coming from the sun splits oxygen gas into free oxygen atoms
(iii) The free oxygen atoms are highly reactive. One oxygen atom reacts with an oxygen molecule to form an ozone molecule.
$\mathrm{O}_{2}+\mathrm{O} \longrightarrow \mathrm{O}_{3}$ (Ozone molecule)
