c. available niches

Population size is directly affected by births, deaths (which relate to food supply), immigration/emigration, and factors like nutrient cycling (detritivore activity) that influence resource availability. "Available niches" describes roles or habitats a species can occupy and affects species distribution and diversity more than the numeric size of a given population.
