Which two statements are possible negative consequences of introducing fish species into a habitat affected by overfishing by humans? A Reintroduding species could help control prey that might overrun an environment. B. The habitat could regain its biodiversity levels by resetting the distribution of fish species. C. The reintroduced species could become invasive if the habitat has already evolved to accommodate the loss of a species. 0. Reintroducing species could provide greater food sources for predators in the habitat increasing the predator poputations. E. Reintroducing species in large quantities could disrupt the distribution of current the species existing in the habitat causing others to die out.
