Answer:(B) decrease protein production
Explanation: nitrogen gas in the atmosphere is the source of nitrogen which is useful to plants.
In the nitrogen cycle, nitrogen gas is converted to it's compounds and then back to it's gas form.
The nitrogenous cycle involves fixation, mineralization, nitrification and denitrification .
In the first three states, nitrogen undergoes changes into a state where it can be absorbed by plants.
In denitrification,nitrates (useful form of nitrogen) are converted into gaseous nitrogen.organisms involved in this process are called denitrifying bacteria eg Pseudomonads sp.
Nitrogen is an important element.
It is useful for the production of protein, DNA, RNA and chlorophyll.
When it is deficient in the soil,it affects the synthesis of proteins and yellowing of leaves due to decrease in chlorophyll
