Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Species Distribution and Biogeography
	**Related Topics**: Endemism, Biodiversity, Conservation Biology
	**Prerequisites**: Basic understanding of species and geographic distribution.
## SOLUTION PATHWAY
**Given Information**:
	The question defines a species found exclusively in a specific geographic area.
**Method & Steps**:
	1. **Understanding Endemism**: A species is considered 'endemic' when it is naturally found only in a particular geographic region and nowhere else on Earth. This region can be a continent, an island, a country, or even a specific habitat type within a larger area.
	2. **Relating to Options**: The term 'endemic' directly matches the question's description.
	3. **Eliminating Other Options**:
		- 'Keystone' species play a crucial role in their ecosystem, but they are not necessarily restricted to a specific area.
		- 'Exotic' species are introduced to an area where they are not native.
		- 'Cosmopolitan' species are found widely distributed across the globe.
	Result: Endemic is the correct term.
## OPTION ANALYSIS
[A] :x: 'Keystone' refers to a species' ecological role, not its geographic restriction.
[B] :x: 'Exotic' species are introduced, not naturally exclusive to an area.
[C] :x: 'Cosmopolitan' species are found widely, the opposite of endemic.
[D] ✓: 'Endemic' perfectly describes a species exclusive to a specific area.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing 'endemic' with 'exotic': Remember, endemic is native and restricted, while exotic is introduced.
		2. Misinterpreting 'keystone': Keystone species are important, but not necessarily geographically restricted.
	**Quick Tips**:
		1. Think of 'endemic' as 'end of the line' – the species is found only at that specific location.
		2. Remember 'cosmopolitan' as 'citizen of the world' – found everywhere.
