Question

final assessment - wildlife population ecology
5 of 10
which of the following is a biotic factor which may impact wildlife populations?
○ extreme temperatures
○ natural disasters
○ pollution
○ parasitism

Explanation:

To determine the biotic factor, we recall that biotic factors are living or once - living components of an ecosystem. Extreme temperatures (abiotic, related to climate), natural disasters (abiotic, geological/meteorological events), and pollution (abiotic, chemical/physical contaminants) are non - living. Parasitism involves a relationship between two living organisms (the parasite and the host), so it is a biotic factor that can impact wildlife populations.

Answer:

Parasitism (the option corresponding to "Parasitism")
