The answer is B. Invasive species are successful in novel environments due to lack of a natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosysem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species. Consequently, the non-native fish species will not invade the new environment unchecked.
