which is a greater threat to a mountain ecosystem: a beetle that kills coniferous trees or a wolf thats hunts and eats deer?

Explanation:

The mountain ecosystems are characterized by coniferous tree species such as pinus, firs, and spruces and species such as deers, bears, and wolves.

A beetle that kills coniferous trees would be a greater threat to the ecosystem than a wolf that hunts and eat deer because the dominant trees in the ecosystem are conifers. Hence, a beetle that kills coniferous trees might end up killing the dominant tree species in the ecosystem and this will gravely affect other plant and animal species within the ecosystem.

Wolves and deers have their niche in the mountain ecosystem already and hence, their populations are naturally limited by limiting factors of the environment. Hence, a wolf that hunts and eats deers would be of a lesser threat to the mountain ecosystem.
