A) Community services decline with decreased species richness in a stepwise fashion.

B) Species that play the same roles in a community can compensate for each other if some are lost under particular conditions

C) Species richness declines even slightly from its natural levels, community services are reduced immediately

D) Community services change as the number of species increases or decreases, but that the direction of change is not predictable.
