Ecosystems in Which Primates Occupy a Large Number of Niches

Ecosystems in which primates occupy a large number of niches:

A) Are more buffered from the impact of primate extinctions than ecosystems in which primates are rare
B) Are more likely to be affected by primate extinctions than ecosystems in which primates are rare
C) Are more likely to also include large numbers of other nonprimate terrestrial mammals than ecosystems in which primates are rare
D) Are more likely to have large predators that keep primate densities down than ecosystems in which primates are rare
