Working on the nitrogen thing, are you???????????
Animals eat the plants that have nitrogen in them. Nitrogen is the key ingredient that make plants green. I know chlorophyll is green, but it is the nitrogen these that is the key.
Animals, obviously breath a lot of nitrogen since it is such a large part of the air (78%), but this is not used by animals and must be removed as a waste (urea) nitrogen salt.

Animals take proteins which is a rich source of nitrogen in their diet. Herbovorus take proteins from their mother's milk, through pulses and few oil seeds. Carnivorous animals get proteins through the bodies of othjer animals.

A large percentage of the air we breathe is nitrogen.

Animals must obtain "fixed" nitrogen through their diets -- proteins and nucleic acids contain "fixed" nitrogen.

They eat.
Breathing is Nitrogendioxide and leaves the body in the same way it came in..no metabolism going on there.

I believe they get it from the water they drink from streams, rivers, etc.
