We get the nitrogen our bodies need by eating food.
By digesting their food in their stomach.
Because our bodies weren't designed to not be doing physical work and to have plenty of food at all times. Way back when people had to go hunt and food wasn't plentiful, our bodies were designed to store extra food in times of plenty, so that we wouldn't starve when times weren't so plentiful.
They depend on the constant waterflow of the ocean through their bodies to obtain food and oxygen and remove wastes.
