The functional role of an organism in the Ecosystem is called?

The functional role of an organism in an ecosystem is called its ecological niche. An ecological niche encompasses all aspects of an organism’s interactions with the biotic and abiotic factors of its environment. It includes the organism’s habitat requirements, its role in energy flow and nutrient cycling, its interactions with other species (such as competition, predation, and symbiosis), and its adaptations to environmental conditions.

Each species within an ecosystem occupies a unique ecological niche, which helps define its place and function within the community. Understanding ecological niches is crucial for studying ecosystem dynamics, species coexistence, and the impacts of environmental changes on biological communities.
