What happens if a disturbance affects one species in a diverse ecosystem?
The ecosystem collapses.
Other functionally similar species may take its place.
All species are affected equally.
The disturbance has no impact.
Why is maintaining ecosystem function important in a diverse community?
It ensures that all species are affected by disturbances.
It ensures that essential functions continue even if some species decline.
It prevents any species from declining.
It stops nutrient cycling.
What is a characteristic of specialist species?
They have broad niches.
