    There isn't enough argon in the atmosphere for it to be biologically important. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.

    Argon (Ar) is a noble gas. Because it does not easily react with other elements to form compounds, it has no biological function.

    because it is inert

    Oxygen and Nitrogen are essential in reactions for life to take place
