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.
C - Historians have different biases and points of view than influence their interpretations
Which is why it it so difficult for historians to arrive at an interpretation of past events that is universally accepted. Most history is also written by the 'victors' so it is typically written from only one POV.
