Answer

Brief Explanations:

Biotic factors are living or once - living components of an ecosystem. In option a, lightning (abiotic) causes the wildfire. In option b, a storm (abiotic) causes the flood. In option c, cattle (a living organism, biotic) overgrazing leads to a landslide, which is a change to the ecosystem due to a biotic factor. In option d, a volcano is an abiotic geological event. So the correct answer is option c.

Answer:

C. a landslide caused by cattle overgrazing
