How do humans get the nitrogen that they need?

Answer: Humans get the nitrogen they need by eating plants or other animals that contain nitrogen.

Explanation: When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

Answer:The most common form of nitrogen in your body is proteins containing mainly carbon, hydrogen, oxygen and nitrogen.
