The submarine has scrubbers. They remove carbon dioxide from the air and break it down to release the oxygen back into the air. There are also a few tanks to supplement the oxygen content if necessary.
A submarine is kept at, or close to, surface air pressure.
The air to replace the water in a submarine's ballast tanks typically comes from high-pressure air banks stored onboard the submarine. These air banks are filled with compressed air from the submarine's air compressors and are used to control the submarine's buoyancy by adjusting the amount of air in the ballast tanks.

The air tanks on a submarine are typically located in the ballast tanks, which are distributed throughout the submarine's hull. These tanks are used to adjust the submarine's buoyancy by filling or emptying them with air or water.

Anti submarine warfare
It floats and sink by changing its buoyancy. The primary method of controling buoyancy is the ballast tanks. The air is let out of them and is displaced by water. This gives the submarine negative buoyancy, which will get the submarine to submerge. By blowing or pumping air into those ballast tanks, the submarine becomes buoyant and rises to the surface.

there are air ducts and fans throughout every submarine
Russian typhoon submarine is bigger than an air bus 380.
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
Actually the submarine will not kill any one, but the rockets and torpedo launched from the submarine kill the people.
