Here's a breakdown of why:
* Introduced Species: This is the most common and widely accepted term. It simply means a species that is not native to a particular area and has been introduced by humans.
* Non-Native Species: Similar to introduced species, this term emphasizes that the species is not naturally found in the region where it has been introduced.
* Exotic Species: This term focuses on the foreign origin of the species. It often implies that the species is from a geographically distant place.
* Alien Species: This term emphasizes the lack of natural connection between the species and the new environment it has been introduced to.
It's important to note that not all introduced species become invasive. Some might adapt well and thrive, while others might struggle to establish themselves. However, the term "invasive species" is used for those introduced species that cause significant ecological or economic harm in their new environment.
