One way could be through natural nitrogen fixation; this is an important
part of the natural nitrogen cycle were nitrogen gas (N2) in the atmosphere is transformed
into ammonia (NH3) in the surface. Some bacteria, the diazotrophs, both living in the soil and in symbiosis with root nodules of some plants, use the enzymes or also known as nitrogenizes, to alter the nitrogen into a practice that can be
used by living organisms.
