Question

non - native species are not from an area. this means that they do not have any natural competitors or predators in the area. why is this a problem? they typically die very quickly. they can out - compete native species.

Explanation:

The question is about non - native species and their impact, which falls under Biology (a subfield of Natural Science). Non - native species, without natural competitors or predators, can grow and reproduce rapidly. Native species, on the other hand, have to deal with natural checks on their population. So non - native species can use resources (like food, space) more effectively than native species, leading to out - competing native species. The option "They typically die very quickly" is incorrect because the lack of competitors/predators would likely lead to population growth, not quick death.

Answer:

The correct option is: "They can out - compete native species."
