Answer:

The nitrogen cycle is important to all living things because all organisms are made up of nitrogen.

Explanation:

The nitrogen cycle describes how nitrogen moves across earth. Nitrogen is found in all living organisms: in amino acids, which in turn make up proteins, in nucleic acids, in adenosine triphosphate (ATP), and in other compounds that are essential for life.

DNA is made up of nitrogen:

ATP is responsible for transporting chemical energy

Humans and all other living organisms would cease to exist without nitrogen, thus its availability and how it cycles through the environment has direct consequences for all living organisms.
