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, <u>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. </u>
<em>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.</em>
