A narrow niche refers to a specific and limited set of environmental conditions in which a species can survive and reproduce successfully.
Generalist Species: A generalist species is able to adapt and survive in a wide range of environmental conditions.
Specialist Species: A specialist species has a narrow niche and requires very specific environmental conditions to survive.
Competitive Exclusion Principle: This principle states that two species with identical niches cannot coexist indefinitely in the same habitat.
