Kudzu is a vine that is native to Japan, but in the United States it is an exotic invader. In many parts of the United States, kudzu is rapidly expanding and outcompeting native species
Explain why kudzu is such an aggressive invader in the United States, but not in its native Japan.
Because kudzu did not evolve in the United States, there are no native predators, parasites, or competitors that coevolved with it. Thus, kudzu found a niche that was unexplored, and other species are not keeping its population in check.
