A. Competition for food
B. The presence of predators

D. An outbreak of wasting disease in elk

Respuesta :

The best answer to this question is:

C. A forest fire that was caused by lightning.

A forest fire could kill for example all the individuals of a certain species in a given area - this would be independent of the population density of the species. All the other factors would affect the population the more, the more dense it is.
