Match the following columns:
| Column I (Bacteria) | Column II (Function) |
| a. Nitrobacteria | 1. Fixation of atmospheric nitrogen |
| b. Ammonifying bacteria | 2. Formation of NH4+ nitrogen |
| c. Denitrifying bacteria | 3. Formation of NO3- nitrogen |
| d. Rhizobium sp. | 4. Formation of N2 nitrogen |
Answer & Solution
Correct Answer:
Option
C
Nitrobacteria are obligate aerobes. It plays an important role in the nitrogen cycle by oxidizing nitrite (NO3-) into nitrate and ultimately nitrogen in the soil.
Ammonifying bacteria convert ammonia into atmospheric nitrogen.
Denitrifying bacteria results in the conversion of nitrates in the soil to free atmospheric nitrogen. Rhizobium species are a group of bacteria that helps in fixing atmospheric nitrogen in plants.
