No, humans do not need nitrogen to breathe for survival. The air we breathe is primarily made up of oxygen, with only a small amount of nitrogen.
We primarily breathe oxygen for survival.
You need to breathe in oxygen and you need to breathe out carbon dioxide.
Yes, breathing is primarily regulated by the levels of carbon dioxide in the blood. When carbon dioxide levels rise, the body signals the need to breathe more to expel excess carbon dioxide and take in fresh oxygen. Conversely, if carbon dioxide levels drop too low, breathing may decrease to retain carbon dioxide.

No, alligators do not breathe through their mouth; they primarily breathe through their nostrils. Their nostrils are located on the top of their snouts, allowing them to breathe while mostly submerged in water. When they need to take a breath, they can quickly surface and inhale through their nostrils while keeping the rest of their body submerged.
Most people primarily breathe out of one nostril at a time, with the dominant nostril switching throughout the day in a cycle known as the nasal cycle.

You need to have a license, and be regulated.
