What would a world whose atmosphere is made up of primarily ammonia be like?

I'm trying to create a fictional world where the primary species breathes in gaseous nitrogen to survive (and hence relies on ammonia). I'm currently working with a planet that would be about the same distance from its star as Earth is from the Sun (as it is most ideal distance for life to flourish). I realize this may be a bit of a stretch, as already Earth has an atmosphere primarily made up of nitrogen, but I'm looking to make the world more structured in gaseous nitrogen than Earth is (of course, still mixing other gaseous elements in the atmosphere such as oxygen and argon).

Would this be possible (even in fiction) or are these specifications going to ensure life is impossible on the planet? Would the weather have to be a certain temperature and type? Could this species survive on earth?

*Edited to make the question simpler, correct wording, and make more precise.
