The term for an organism's role within its ecosystem is known as its niche. The niche encompasses not just the organism's habitat but also its interactions with other organisms, including competition, predation, and symbiosis. Each species occupies a unique niche, allowing for diverse biological communities. Understanding ecological niches is essential for conservation efforts, as it helps identify how species depend on one another and the potential impacts of environmental changes. Moreover, studying niches can inform management strategies for preserving biodiversity and ecosystem stability.
