Answer:
Biotic and abiotic factors both determine that a population can live or not in a particular place.
Abiotic factors include air, water, soil, minerals, temperature et cetera. The basic needs of any living organism include air, water, food and shelter which can not be fulfilled without these abiotic factors.
Biotic factors include all the living organisms present in that area. The ecological interactions (such as mutualism, predation, symbiosis et cetera) between organisms determine the survival of any population in a given area or ecosystem.
