When two species compete for similar resources, resource partitioning can alter the niche of the species that compete. The figure below shows an example of this. Resource partitioning results in:
A)individuals of each species sharing the resources that they both exploit.
B)individuals of each species hybridizing in the region of overlap.
C)a move from the fundamental niche to the realized niche for both species.
D)a move from the realized niche to the fundamental niche for both species.

Resource partitioning causes each species to find a niche that allows them to coexist and reduce competition for resources. This results in a shift from the fundamental niche (the total range of environmental conditions that are suitable for the species) to the realized niche (the actual range of environmental conditions in which the species exists). This allows both species to survive and thrive in their respective niches.
