Options:
Answer:
D
Solution:
| Macronutrients | Micronutrients or Trace Elements |
| Examples : Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulphur, Potassium, Calcium and Magnesium. | Examples : Iron, Manganese, Copper, Molybdenum, Zinc, Boron, Chlorine and Nickel. |
Following steps are involved in nitrification :
Oxidation of ammonia to nitrite (by Bacteria -Nitrosomonasand/orNitrococcus)
Further oxidation of nitrite to nitrate (by Bacteria -Nitrobacter)
Denitrification: Some bacteria such asThiobacillus denitrificans, Pseudomonas aoruginosa andMicrococcus denitrificansalso occur in the soil which convert the nitrate and ammonia into atmospheric free elemental nitrogen.
