Answer: c. ability to become highly abundant in most ecosystems.
Step-by-step explanation:
The prokaryotic microbes are small tiny creates which remain invisible to the naked eyes. These require special instruments to be observed. The reproduce at a considerable rate and they have the tendency to spread all over the world in a short time. Their reproduction is simple that is division of the parent cell into daughter cells. This facilitates their abundance in most ecosystems initiating with colonization in living organisms.
The given situation indicates that rapid reproduction facilitates the microbes to become abundant in the ecosystem.
