What's the relationship between nitrogen fixation, nitrification, and denitrification?

Question

Thanks in advance for any help! :D

Answer 1

1 ) Nitrogen Fixation =Nitrogen fixation is the process by which nitrogen is taken from its natural, relatively inert molecular form (N2) ( Nitrogen gas from the air)in the atmosphere and converted into nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide).

  

(((Given above is the definition of that process)))

Nitrogen fixation is performed naturally by a number of different prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria.

Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations with diazotrophs.

Nitrogen fixation also occurs as a result of non-biological processes.

These include lightning, industrially through the Haber-Bosch Process, and combustion.

Biological nitrogen fixation was discovered by the Dutch microbiologist Martinus Beijerinck.

2 ) Nitrification ==Nitrification is the biological oxidation of ammonia with oxygen into nitrite followed by the oxidation of these nitrites into nitrates.

((( Above is the definition of Nitrification )))

Degradation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil. This process was discovered by the Russian microbiologist, Sergei Winogradsky.

3 ) Denitrification ==Denitrification is a microbially facilitated process of dissimilatory nitrate reduction that may ultimately produce molecular nitrogen (N2)

ALL THE THREE PROCESSES MENTIONED ABOVE FORM THE PART OF NITROGEN CYCLE IN NATURE .
