<speciesfyi-glossary slug="niche"></speciesfyi-glossary>Definition
The role and position a species occupies in its ecosystem, including all interactions with biotic and abiotic factors.
Detailed Explanation
No two species can indefinitely occupy the same ecological niche — this competitive exclusion principle drives niche differentiation. Darwin's finches on the Galápagos famously partitioned food resources by evolving different bill shapes, each occupying a distinct dietary niche. Understanding niches is essential for predicting competition, coexistence, and the impact of invasive species.
