# of species vs body mass

Here are some graphs:

It's obvious why the number of species that have smaller body sizes are greater in number.
However, once we get into organisms with mass smaller than 100g, it seems to decrease. Why? One would assune it'd keep increasing, no?
Furthermore, would the trend continue for microbials?
