Verified step by step guidance1
Understand the term 'endemic species': An endemic species is one that is native to and restricted to a specific geographic location. It is not found naturally anywhere else in the world.
Compare the options provided in the question to the definition of an endemic species.
Option 1: 'A species that is found on every continent' does not match the definition because endemic species are restricted to specific areas, not widespread globally.
Option 3: 'A species that has been introduced to a new area by humans' does not match the definition because introduced species are not naturally native to the area; they are brought there by human activity.
Option 4: 'A species that migrates between different regions each year' does not match the definition because migratory species move between regions and are not restricted to one specific geographic location.
