What is an example of exotic species?
Exotic species are those that have been intentionally or unintentionally introduced by humans into an ecosystem in which they did not evolve.

No human intervention brought a native species to the area or influenced its spread to that area. Native species are also sometimes called indigenous species.
How do non-native species affect the environment?
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
