The species which are confined to a particular area are called-
Endemic species
Endemic Species Explained
The question asks to identify the term for species that are restricted to a specific geographical area. Understanding the definitions of different types of species is key to answering this question correctly.
What are Endemic Species?
Endemic species are types of plants or animals that are found exclusively in a particular geographical region, specific habitat, or isolated area. They do not naturally occur anywhere else in the world. This confinement can be due to various factors like geographical barriers (e.g., islands, mountain ranges), specific climatic conditions, or unique ecological requirements. A classic example would be the kangaroos in Australia or certain lemur species found only in Madagascar.
Analyzing Other Species Classifications
Let's look at why the other options do not fit the description of species confined to a particular area:
- Pandemic species: This term is not typically used for a species itself. "Pandemic" refers to a disease epidemic that has spread across a large region, multiple continents, or even worldwide. It describes the widespread nature of a disease, not a species confined to an area.
- Extinct species: An extinct species is a type of organism that no longer exists on Earth. Its last individual has died, and there is no remaining living member of that species anywhere in the world. This classification relates to the existence or non-existence of a species, not its geographical confinement.
- Vulnerable species: A vulnerable species is a species that is at a high risk of extinction in the wild in the near future. This categorization is based on population decline, habitat degradation, or other threats to its survival. While vulnerable species might have limited ranges, the primary definition focuses on their conservation status rather than their exclusive confinement to an area.
Comparison of Species Terms
To further clarify, here is a comparison of the terms presented:
| Term | Definition | Example |
|---|---|---|
| Endemic species | Species found exclusively in a particular geographical area or habitat. | Lemurs (only in Madagascar), Koalas (only in Australia) |
| Pandemic species | (Not a standard term for species classification) Refers to a widespread disease. | N/A (applies to diseases, not species) |
| Extinct species | A species that no longer exists on Earth. | Dodo bird, Passenger Pigeon |
| Vulnerable species | A species at high risk of extinction in the wild. | Giant Panda, Bluefin Tuna |
Conclusion
Based on the definitions, the term that accurately describes species confined to a particular area is Endemic species. These species are unique to their specific location and are often of significant conservation interest due to their restricted distribution.
