Species found exclusively in a specific area
Explanation
In ecology and biogeography, species are often classified based on their distribution patterns. Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country, or other defined zone, or habitat type.
Option Analysis:
- Species found in multiple geographical zones is incorrect: Species found in multiple geographical zones or distributed globally are referred to as cosmopolitan species (e.g., the housefly or humans).
- Species found exclusively in a specific area is correct: A species confined naturally to a particular geographical region is described as an endemic species. For example, Lemurs are endemic to Madagascar, and the Asiatic Lion is endemic to the Gir Forest in India.
- Species introduced from a foreign habitat is incorrect: Species introduced from a foreign habitat are known as exotic, alien, or introduced species. If they spread unchecked and harm the local ecosystem, they are termed invasive species (e.g., Water Hyacinth in India).
- Species that are extinct in the wild is incorrect: Species that no longer exist in their natural habitat but survive in captivity (zoos, botanical gardens) are classified as Extinct in the Wild under the IUCN Red List categories.
Key Takeaway:
Endemic species are those strictly restricted to a specific geographical area and are not found naturally in any other part of the world.
