Final answer:
Predation is a biotic factor that can limit the distribution of organisms because it involves interactions between living entities, unlike temperature, salinity, and moisture levels, which are abiotic factors.
Step-by-step explanation:
The biotic factor that could limit distribution from the options provided is C. Predation. Biotic factors are living components of an ecosystem that can influence the distribution and abundance of organisms. Predation is a biotic factor because it involves interactions between living organisms wherein a predator feeds on its prey, potentially affecting the prey species' distribution and population size.
biotic factors like temperature, salinity, and moisture levels are non-living physical and chemical elements of the environment that can also limit the distribution of organisms, but they are not considered biotic.
