1)
The term denitrification refers to
Conversion of ammonia into nitrates
Nitrogen and hydrogen and combine to form ammonia
Reduces nitrates to nitrogen gas there by replenishing nitrogen in the atmosphere.
Nitrogen is converted to ammonium
2)
Which of the following can oxidize the conversion of nitrites into nitrates?
Nitrosomonas
Nitrobacter
Pseudomonas
Clostridium
3)
The process which describes the oxidation of ammonium compounds to nitrites and the further oxidation of nitrites to nitrates
Nitrification
Nitrogen fixation
Assimilation
Ammonification
4)
Example of nitrifying bacteria
Nitrosomonas
Nitrosococcus
Nitrobacter
All the above
5)
Nitrogen is an important element in
Vitamins
Carbohydrates
Protein
Lipids
6)
Organic compounds found in the dead organic matter is converted into ammonia as a result of
Ammonification
Decomposition
Absorption
Nitrogen fixation
7)
Plants can use Nitrogen in the form of
Nitrates
Ammonia
All the above
Nitrogen dioxide
8)
Nitrifying bacteria are present in
Plant leaf
Plant stem
Plant root
None of the above
9)
Animals such as rabbit, cow etc absorbs nitrogen through eating plants.
True
False
10)
