Ecological Niche - SS1 Biology Lesson Note

An ecological niche refers to the specific role and position that a species or population occupies within an ecosystem. It encompasses the interactions between an organism and its physical environment, as well as its interactions with other species. The niche of an organism includes its habitat requirements, resource utilization, feeding strategies, reproductive behaviors, and responses to environmental conditions. Each species has its own unique niche, allowing it to carve out a specialized ecological space and avoid direct competition with other species. The concept of ecological niche highlights the intricate web of relationships and adaptations that shape the structure and functioning of ecosystems, and it plays a crucial role in understanding species coexistence, biodiversity, and ecosystem dynamics.
