What is an invasive species?
Correct!
Invasive species are non-native animals, plants, fungi, or other organisms that spread in a new area and can cause ecological or other significant harm there. Not every introduced species is automatically invasive. It becomes problematic, for example, when it displaces native species, uses their food, spreads diseases, or substantially changes habitats. Well-known examples include raccoons in parts of Europe, the Asian hornet, the signal crayfish, and plants such as Japanese knotweed.
A non-native species is generally called invasive when it can cause significant harm.
