Question

How are microorganisms involved in the movement of nitrogen from the atmosphere to the bodies of other organisms? Why can’t other organisms just get nitrogen from air?

Answer 1

Microorganisms that are involved in the nitrogen cycle are able to break the triple of elemental nitrogen using special enzymes that they have developed and make ammonium. Other organisms like plants are unable to break the triple bond and therefore rely on these microorganisms so that they can absorb the ammonia
