A family member of yours who has never studied about this tries to understand
the cartoon pictures but is unable to understand it. He knows that there are no
such living forms in atmosphere but he is not able to understand names like 0,02
and O, and also the
process explained.
How would you explain it to that family member? State in your own words.
