Statement A : Apart from carbon, hydrogen and oxygen, nitrogen is the most prevalent element in living organisms. Statement B : Plants do not compete with microbes for the nitrogen that is available in soil.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.

Some ammonia volatilises and re-enters the atmosphere but ____ of it is converted into nitrate by soil bacteria.
1 All
2 Most
3 Negligible amount
4 None of the above.
Explanation:
Decomposition of organic nitrogen of dead plants and animals into ammonia is called ammonification. Some of this ammonia volatilises and re-enters the atmosphere but most of it is converted into nitrate by soil bacteria.
