Answer:
The correct answer is - speciation is sympatric.

Answer: Vestigial structures
Explanation: Vestigial structures are an anatomical feature or behavior that no longer seem to have any purpose in the present form of an organism in the given species. Usually, they are often parts of the body that used to preform important functions in earlier forms of the organism.
If an invasive species is added into a food chain/web, it becomes overpopulated/a pest because it has no natural predators.
It can also disrupt the food chain/web by eating the food supplies of the native organism leading to competitions.
