An ecological niche refers to the role and position a species occupies in its environment, encompassing its habitat, resource use, and interactions with other organisms. Niche differentiation allows multiple species to coexist by reducing competition for resources. Each species has unique adaptations that enable it to thrive in specific niches, contributing to biodiversity and ecosystem functioning. Understanding ecological niches is essential for conservation efforts, as it helps in maintaining the balance of ecosystems and protecting various species.
