|
|
Competitive exclusion results in the success of the superior species.
|
|
|
Slight variation in niche allows closely related species to coexist.
|
|
|
Two species can coevolve and share the same niche.
|
|
|
Species diversity is maintained by switching between prey species.

Detailed explanation-1: -Resource partitioning occurs when species divide a niche to avoid competition for resources. It include slight variations in niche allow similar species to coexist. Thus, the correct option is B.
Detailed explanation-2: -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.
Detailed explanation-3: -Resource partitioning The result of this kind of evolution is that two similar species use largely non-overlapping resources and thus have different niches. This is called resource partitioning, and it helps the species coexist because there is less direct competition between them.
Detailed explanation-4: -If two species compete for a limited resource and utilise it in the same way, i.e. occupy the same niche, then they cannot coexist. Resource partitioning is an evolutionary adaptation to reduce competition and favours coexistence.
Detailed explanation-5: -The term niche partitioning refers to the process by which natural selection drives competing species into different patterns of resource use or different niches (Hector and Hooper, 2002; From: Advances in Ecological Research, 2016.
