which of the following is incorrect about the nitrogen cycle? a. nitrate and nitrite reductases in denitrifying bacteria convert
Serjik [45]

The incorrect statement about the nitrogen cycle is option A: nitrate and nitrite reductases in denitrifying bacteria convert ammonia to nitrogen gas.

The biological nitrogen fixation (BNF) is the process by which atmospheric nitrogen is changed into ammonia, and the nitrogen-fixing bacteria are known as diazotrophs. Fixation, ammonification, nitrification, and denitrification are significant nitrogen cycle processes. Ammonia is converted to nitrites and then to nitrates which are absorbed by plants with the help of their roots. Therefore, option A is incorrect.

Through bacteria that fix nitrogen from the atmosphere, nitrogen enters the living world. Soil bacteria convert this nitrogen and nitrogenous animal waste back into gaseous nitrogen, supplying the organic nitrogen required by terrestrial food webs.
