Often the exotic species has fewer natural enemies in the new environment but competes for the same food supply and other necessities as the native species it displaces. Sometimes the exotic species is more adaptable or more aggressive and so pushes out a native species. Sometimes the exotic species reproduces at a higher rate or more successfully than does the native species.
