A species is considered introduced when its transport into an area outside of its native range is human mediated. Introductions by humans may be either intentional or accidental. In the U. S. Many economically important species have successfully been introduced and managed: they have not become invasive species. Identify the statement that is NOT CORRECT regarding the positive effects of introduced species.

They have become invasive species.

Explanation:

The introduction of new species in the new area make the specie invasive if there is no predator is present in that ecosystem because the predator helps in the controlling of the population of that invasive species. The big example of invasive species is rabbit in the Australia where rabbit become invasive when there is no predator is present in that region so they increase in population and destroy all vegetation of that region. So if there is no predator of a newly introduced species, it become invasive in future.
