Depends somewhat on altitude, but generally nearly 80% is nitrogen.

The atmosphere of the Earth is primarily nitrogen, which is about 78% of air by volume. Nearly 21% is oxygen, 1% is argon, and the remainder consists of trace gases and carbon dioxide.
Argon makes up roughly one percent of Earth's atmospheric gases. A more precise/exact amount would be 0.93%
I don't think the ocean produces nitrogen or oxygen for that matter. Nitrogen comes from fusion (in a star, hydrogen turns into helium, which in turn changes into heavier elements). The ocean may store some nitrogen as a dissolved gas and nitrogen in the form of compounds such as NH3 and other soluble salts.

Without nitrogen in the atmosphere, we would be breathing in nearly pure oxygen, which would be fatal.

Argon makes up about .93 percent of the Earths atmosphere. Hope this helps! (:
Nitrogen.
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
Nitrogen is necessary for life on earth. Without nitrogen, which makes up some 78% of the earth's atmosphere, we would be breathing in nearly pure oxygen and that would be fatal.

Nearly all of the nitrogen in a diet is present as amino acids in proteins. The average nitrogen content of proteins was found to be around 16 percent.
