Microbes which are responsible for conversion of nitrites into nitrates belong to the kingdom
1 Monera
2 Eubacteria
3 Protista
4 Fungi
Explanation:
The nitrite is oxidised to nitrate with the help of the bacterium Nitrobacter. Bacteria are the sole members of the Kingdom Monera. Hence, Microbes which are responsible for conversion of nitrites into nitrates belong to the kingdom Monera.

How many of the following are not the source of atmospheric nitrogen oxides? Lightning, Industrial combustions, forest fires, automobile exhausts and power-generating stations, ultraviolet radiation.
1 4
2 3
3 2
4 5
Explanation:
Lightning and ultraviolet radiation are not the source of nitrogen oxides they provide energy for the conversion of nitrogen into nitrogen oxides.

Identify the pair of bacteria which carries out denitrification.
1 Pseudosomonas and Thiobacillus
2 Nitrosomonas and Nitrococcus
3 Nitrococcus and Nitrobacter
4 Pseudomonas and thiobacillus
Explanation:
Nitrate present in the soil is also reduced to nitrogen by the process of denitrification. Denitrification is carried by bacteria Pseudomonas and Thiobacillus .

The nitrifying bacterias are
1 Photosynthetic
2 Chemoautotrophs
3 Saprophytic
4 Heterotrophs
Explanation:
Ammonia is oxidised to nitrite by the bacteria Nitrosomonas and/or Nitrococcus. The nitrite is further oxidised to nitrate with the help of the bacterium Nitrobacter. These steps are called nitrification. These nitrifying bacteria are chemoautotrophs.
