5.I measure the use of nuts, trees and nesting
materials by two species of squirrel and find some strong overlaps in the uses
of nesting materials in particular. Is
it safe to conclude that these two species are competitors? Why or why not?
If two species have a high demand for a material, and the supply runs low, it is safe to assume they are natural competitors because they are in need of the same material. This happens by the process of natural selection, or "survival of the fittest", where the species that is better equipped for a situation survives.
