Answer:
Invasive species
Explanation:
Any organism that enters a habitat where it does not belong is an invasive species. There are many plants that have been brought from other countries, and sometimes they take root in the new habitat.
The same thing with animals and migration patterns, if a species moves to a new habitat it is known as an invasive species.
The danger with this phenomenon is that sometimes the invasive species will compete with the natural occuring wildlife.
