  6. ECOLOGICAL NICHE An ecological niche describes how an organism or population responds to the distribution of resources and competitors . The way of life of a species. The optimum range refers to the abiotic factors at which the organisms functions best. Physiological stress refers to outside the preferred niche/optimum range. Looking at niches (worksheet)
