Question

In a prairie, increased plant species richness usually means
A) Decreased insect herbivore richness
B) Increased insect herbivore richness
C) Increased insect predator richness
D) a and b
E) b and c

Accepted Answer

Increased plant species richness in a prairie typically leads to increased insect herbivore richness because a greater variety of plants provides more niches and food sources for different types of herbivores. This, in turn, can lead to increased insect predator richness as more diverse prey populations support a wider array of predators.
