Nitrifying bacteria play a crucial role in the nitrogen cycle by:
Converting atmospheric nitrogen into ammonia
Reducing nitrate to nitrite and then to nitrogen gas
Oxidizing ammonia to nitrite and then nitrate
Converting organic nitrogen into ammonia
The process of conversion of ammonia to nitrite is called:
Nitrogen fixation
Nitrification
Denitrification
Ammonification
Which of the following microorganisms are primarily responsible for the conversion of nitrite to nitrate in the soil?
Nitrosomonas
Nitrobacter
Rhizobium
Azotobacter
Thiobacillus bacteria are beneficial in which process?
Nitrogen Fixation
Photosynthesis
Bioleaching/Biomining
Methanogenesis
Which of the following processes is facilitated by Thiobacillus bacteria?
Phosphorus solubilization
Sulfur oxidation
Iron reduction
Methane production
Certain bacteria living in the soil poor in oxygen, convert nitrates into nitrites and then to free nitrogen and such bacteria are termed as
Nitrogen fixing bacteria
Denitrifying bacteria
Ammonifying bacteria
Saprophytic bacteria
Bacterium which reduces nitrates in soil to nitrogen is
Nitrosomonas
Pseudomonas
Rhizobium
Clostridium
