Living organisms can use Nitrogen (N2) as it occurs in the atmosphere.

1.	Living organisms can use Nitrogen (N2) as it occurs in the atmosphere.(a) True(b) FalseI have been asked this question in semester exam.The doubt is from Various Cycles of Environment in section Other Major Topics in Civil Engineering of Basic Civil Engineering
Answer» The correct CHOICE is (b) False For explanation I WOULD say: The living ORGANISMS cannot use N2 to synthesise organic compounds. N2 is converted to NH3 by nitrogen fixing bacteria and then to nitrate by NITRIFYING bacteria which can then be USED by organisms.
