Lightening and UV radiation can cause a reaction between nitrogen and oxygen and produces
1 \(\mathrm{NO}\)
2 \(\mathrm{NO}_{2}\)
3 \(\mathrm{N}_{2} \mathrm{O}\)
4 All of these
Explanation:
In nature, lightning and ultraviolet radiation provide enough energy to convert nitrogen to nitrogen oxides \(\left(\mathrm{NO}, \mathrm{NO}_{2}, \mathrm{~N}_{2} \mathrm{O}\right)\).

Which of the following is prevalent element in living system besides carbon, hydrogen and oxygen?
1 Nitrogen
2 Scandium
3 Vanadium
4 Molybdenum
Explanation:
Apart from carbon, hydrogen and oxygen, nitrogen is the most prevalent element in living organisms. Nitrogen is a constituent of amino acids, proteins, hormones, chlorophylls and many of the vitamins.

Nitrogen is a limiting nutrient for ____
1 Natural and agricultural eco-system.
2 Only natural eco-systems
3 Only agricultural eco-systems
4 None of the above
Explanation:
Plants compete with microbes for the limited nitrogen that is available in soil. Thus, nitrogen is a limiting nutrient for both natural and agricultural eco-systems.

Thiobacillus is a group of bacteria helpful in carrying out
1 Nitrogen fixation
2 Chemoautotrophic fixation
3 Nitrification
4 Denitrification
Explanation:
Thiobacillus denitrificans cause denitrification. i.e., conversion of oxides of nitrogen to free \(\mathrm{N}_{2}\).
