Notes:
The conversion of N2 to ammonia is known as Nitrogen fixation.
14. Which bacteria supply ammonia to soil?
[A] Rhizobium
[B] Lactobacillus
[C] Streptomyces
[D] Campylobacter
Show Answer
Correct Answer: A [Rhizobium]
Notes:
Rhizobium is an organic fertilizer. Biofertilizers are substances that contain microorganisms that, when applied to the soil, increase the amount of nutrients. It also enhances the growth of plants.
15. The process by which ammonia is converted into nitrate is__?
[A] Nitrogen-fixation
[B] Ammonification
[C] Denitrification
[D] Nitrification
Show Answer
Correct Answer: D [Nitrification]
Notes:
The Process by which ammonia is converted into nitrate is called Nitrification. It can be done in two steps that involve Nitrite formation and Nitrate formation.
16. Which bacteria are involved in the oxidation of ammonia into nitrate?
[A] Acetobactor
[B] Nitrococcus
[C] Nitrobacter
[D] Both Nitrococcus and Nitrobacter
Show Answer
Correct Answer: D [Both Nitrococcus and Nitrobacter]
Notes:
The conversion of ammonia into nitrate is a two-step process where ammonia is initially oxidised to nitrite by Nitrosomonas or Nitrococcus, this nitrite is then further oxidised to nitrate by Nitrobacter. This series of conversion is known as nitrification and is an important part of the nitrogen cycle, which is crucial for primary productivity in many ecosystems.
17. ‘Green Hydrogen and Ammonia Policy’ has been launched by which ministry?
[A] Ministry of Power
[B] Ministry of New and Renewable Energy
[C] Ministry of Environment, Forest and Climate Change
[D] Ministry of Science and Technology

[A] Palahalli
[B] Halagur
[C] Belagola
[D] Basaralu
Show Answer
Correct Answer: C [Belagola]

19. As per a recent study by the IIT-Kharagpur, which region of India is named as the global hot-spot of atmospheric ammonia (NH3)?
[A] Southern Coastal region
[B] Indo-Gangetic Plain
[C] Deccan Plateau
[D] Western Ghats
Show Answer
Correct Answer: B [Indo-Gangetic Plain]
Notes:
According to researchers at the Indian Institute of Technology (IIT) Kharagpur, the Indo-Gangetic Plain (IGP) is the global hot-spot of atmospheric ammonia (NH3).
This is due to concentrated agricultural activities and fertilizer production in the region. The satellite data of agricultural emissions show that atmospheric ammonia is related with total fertilizer consumption and temperature.

[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
