An invasive species of plant is introduced that outcompetes all local plants.

Answer 1

The factor that would be considered a micro-effect on biodiversity is:

An invasive species of plant is introduced that outcompetes all local plants.

Micro-effects typically refer to changes that influence individual species or small populations, as opposed to larger ecological changes that might affect broader ecosystems (macro-effects). The introduction of an invasive species directly impacts local plant populations and can alter the dynamics within a specific ecosystem, thus representing a micro-effect.
