Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.
Those molecule bases can be sequenced differently, leading to different animals. Please Mark Brainliest!!!
