Nitrogen, you can't survive on it obviously but you breath it in every day it is the most abundant gas in the atmosphere followed by oxygen I think.
Nitrogen cycle
In air there is 20.98% Oxygen, so that's what we inhale. We exhale 16% of this Oxygen; hence why cardiopulmonary resuscitation is possible.
Rhizobium Bacillus is the bacteria that converts nitrogen gas in the air into ammonia. It plays an important role the nitrogen cycle by fixing nitrogen which is otherwise an inert gas.
Plant can not use nitrogen "air" (gas), it must be "fixed" , a nitrous compound.
