Topic: competition for a single resource
Difficulty: medium
The resource requirements of two plant species, A and B, have been carefully studied. Researchers have determined the levels of a particular resource that will support equilibrium levels of each species. Species A needs more of this resource to maintain equilibrium than does species B. When these two species are set in competition (under conditions in which this resource is limiting), what is likely to happen to the populations of species A and B?

Question

Quizplus · Accepted Answer

Since species A requires more of the limiting resource to maintain equilibrium, in a competitive environment, species B will be able to survive with less of the resource and outcompete species A. Therefore, species B will displace species A.
