What does A and B represent in the given diagram
What does A and B represent in the given diagram
Open in App
Solution
The correct option is C denitrification (A), ammonification (B)
A represents denitrification and B represents ammonification.
The given diagram represents the nitrogen cycle. Nitrogen cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere.
Nitrogen cycle includes various processes like nitrogen fixation, nitrification, ammonification and denitrification.
Denitrification is the process in which nitrates present in the soil are reduced to nitrogen. The bacteria that help in this process are Thiobacillus denitrificans and Pseudomonas denitrificans
The organic nitrogen of dead plants and animals (decaying biomass) undergoes decomposition to release ammonia. This process is called ammonification. It is carried out by bacteria such as Bacillus vulgaris.
Nitrification is the process of oxidation of ammonia into nitrite by bacteria such as Nitrosomonas and later the nitrite is oxidised to nitrate by bacteria such as Nitrobacter.
Nitrogen fixation is the conversion of atmospheric nitrogen into compounds of nitrogen like nitrates and ammonia.
