Aspecies that is only found in one location on earth is called a/an:
invasive species
endemic species
threatened species
native species

The answer is Endemic Species

Endemic species refer to those that can only be found in a particular geographic location such as a specific island, habitat, or other pre identified zones. To be categorized as an endemiz species, that species must only be found in 1 specific location and nowhere else in the world

One of the example of endemic species is Comodo Dragon that can only be found in Comodo Island, Indonesia
