Which describes a population depending on an abiotic factor?

As the options are not mentioned for the question, lets have a look at the abiotic factors generally.

Explanation:

An ecosystem includes the biotic and abiotic factors. The biotic factors are the living components of the ecosystem. The abiotic factors are the non- living components of the ecosystem. The abiotic factors include factors like water, sunlight, soil etc of the ecosystem. Both the biotic and abiotic components are equally important in the survival of an organism in the ecosystem.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
