An abiotic factor is not associated with living organisms. Environmental abiotic factors include sunlight, temperature, wind and rainfall. For any plant living at the base of a waterfall, we can expect a very moist environment for a high proportion of the time. Therefore, the abiotic factor in this case is high moisture.
