B)bacteria.
C)fungi.
D)mammals.

Question

Quizplus · Accepted Answer

The organisms responsible for most of the conversion of atmospheric nitrogen to a usable form are bacteria. Specifically, nitrogen-fixing bacteria convert atmospheric nitrogen (N₂) to ammonium (NH₄⁺) or nitrate (NO₃⁻), which can then be used by other organisms. Photosynthetic plants and fungi do not play as significant a role in this process. Mammals also do not have the ability to convert atmospheric nitrogen to a usable form.
