The nitrogen cycle

what is the nitrogen cycle ?

The essential biogeochemical process by which atmospheric nitrogen is converted into usable chemical compounds and then cycled between the atmosphere, soil, and living organisms.

what are the 2 nitrogen fixing bacteria ?

Rhizobium and Azotobacter.

what are the functions of Rhizobium and Azotobacter ?

are able to convert gaseous nitrogen into ammonium ions ( NH4 + )

how’s ammonium nitrified ?

By Nitrifying bacteria.

what are the 2 nitrifying bacteria called ?

Nitrosomonas and nitrobacter species

what is the function of Nitrosomonas ?

Converts ammonium to nitrites ( NO2 - )

what is the function of Nitrobacter species ?

convert nitrites to nitrate ion ( NO3 - )

Nitrosomonas and nitrobacter species they are both ?

Highly soluble and can be absorbed by roots.

Give an example of denitrifying bacteria ? and its functions

Thiobacillus denitrfcans , uses nitrates for respiration and return gaseous nitrogen to the atmosphere.

what is chemoautotrophs ?

It’s a microorganisms that uses inorganic chemical as their energy source / convert them into organic compounds.
