All of the options listed can influence the survival of an organism in an ecosystem, but the question specifically asks for a nonliving factor. The nonliving factors from the options provided are:
- Amount of sunlight
- Amount of water
- Soil composition
- Temperature range
The option "other organisms" refers to living factors, so it does not qualify as a nonliving factor.
Therefore, any of the following can be considered a correct answer, as they are all nonliving factors that influence survival:
- Amount of sunlight
- Amount of water
- Soil composition
- Temperature range
