Question

colorado has a vast population of lodgepole pines. a population of lodgepole pines has been killed in a section of the forest. what is a possible limiting factor of that population?
devastation by the pine bark beetle
colorados long history of acidic soils
genetic variability
shallow root system

Explanation:

Pine bark beetles can infest and kill lodgepole pines. Acidic soils in Colorado are not a common - known immediate killer of lodgepole pines. Genetic variability is not a limiting factor that would directly kill a population. A shallow root system is a characteristic, not a common immediate cause of large - scale death.

Answer:

devastation by the pine bark beetle
