Which of the following is an example of a biotic factor?

Biotic factors are living components of an ecosystem that affect the organisms within that environment. Predation by wolves is a prime example of a biotic factor because it involves interactions between species. Wolves can significantly influence the populations of their prey, which can, in turn, affect the structure and dynamics of the entire ecosystem.

In contrast, soil composition, amount of sunlight, and water availability are considered abiotic factors. These are non-living chemical and physical parts of the environment that influence living organisms and the functioning of ecosystems. While they are critical for survival and play crucial roles in the ecosystem, they do not involve interactions among living organisms.
