It doesn't need diversity, it just needs those particular organisms.
Any organism that needed biodiversity in the desert wold be in a
bad way - deserts have relatively low biodiversity.

What flower is that, anyway? I'd never heard of any that needed
more than one species of pollinator, just of ones that could
use multiple species.

A few plankton participate in trace element chemical cycles, and
they genuinely are important. Most, though, are like plants,
and readily substitute for each other.
