The prefix Micro- indicates which meaning?

Explanation:
Micro- signals that something is small in size. In medical terminology prefixes modify the root to show size, amount, or location, and micro- specifically indicates a smaller scale. Think of microscope (an instrument for viewing small things), microorganism (a tiny organism), or microgram (a very small unit of mass). The other meanings come from different prefixes: macro- means large, di- or bi- means two, and pan- or omni- means all. Because micro- directly conveys small, it is the correct meaning.
