The concept of ecological niches refers to the role and position a species occupies in its ecosystem, including all interactions with biotic and abiotic factors. It encompasses not just where an organism lives (its habitat) but also how it obtains resources, interacts with other species, and contributes to energy flow and nutrient cycling. Niche differentiation can reduce competition and promote biodiversity. Understanding ecological niches helps ecologists predict how changes in the environment or species interactions might impact community dynamics and overall ecosystem health.
