b) Resource partitioning occurs when two species coexist in spite of apparent competition for the same resources. Close study would reveal that they actually occupy slightly different niches.

Where does resource partitioning happen?

Lesson Summary

When species divide a niche to avoid competition for resources, it is called resource partitioning. Sometimes the competition is between species, called interspecific competition, and sometimes it's between individuals of the same species, or intraspecific competition.

Why would resource partitioning happen?

Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche. In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another.
