What aspect of an ecological niche distinguishes it from a habitat?

The distinguishing aspect of an ecological niche lies in the resources utilized and the interactions with other species. While a habitat refers to the physical environment in which an organism lives, the niche encompasses the role that the organism plays within that environment. This includes how it obtains food, where it finds shelter, its behavioral patterns, and its relationships with other organisms, such as predators, prey, and competitors.

In ecological terms, the niche encompasses both the biotic (living) and abiotic (non-living) components that affect how the species interacts with its environment and with other species. For example, consider two species that occupy the same habitat but utilize different resources—their niches will differ based on their interactions and roles. This concept is essential as it demonstrates how biodiversity contributes to ecosystem function and stability.

The focus on resources and interactions rather than just the physical space occupied by the organism reinforces the complexity of ecological relationships, which is paramount for understanding ecological dynamics, species coexistence, and the overall functioning of ecosystems.
