Which of the following pairs is correctly matched? | List I | List II 1. | Flora | Plants found in a particular area 2. | Fauna | Animals found in a particular area 3. | Endemic | Species found everywhere 4. | Extinct | Species whose numbers are diminishing Select the correct answer using the code given below:

The correct option is 1 and 2 only Explanation Biodiversity terminology classifies organisms based on their biological kingdom, geographical distribution, and conservation status. Understanding these definitions is fundamental to biogeography and conservation biology. - Pair 1 is correctly matched: Flora refers to the collective plant life occurring in a particular region, habitat, or geological period. It encompasses all indigenous native plant life of a specific area. - Pair 2 is correctly matched: Fauna refers to the collective animal life found in a particular region or time period. - Pair 3 is incorrectly matched: Endemic species are those found exclusively in a specific geographical area and nowhere else in the world (e.g., the Asiatic Lion in Gir Forest). Species that are found almost everywhere are termed Cosmopolitan species. - Pair 4 is incorrectly matched: Extinct species are those that no longer exist anywhere on Earth (e.g., the Dodo). Species whose numbers are diminishing and are at risk of extinction are classified as Endangered or Threatened. Key Takeaway: Endemism denotes strict geographical restriction to a specific locale, whereas extinction signifies the complete and irreversible disappearance of a species globally.

Solution

The correct option is

1 and 2 only

Explanation

Biodiversity terminology classifies organisms based on their biological kingdom, geographical distribution, and conservation status. Understanding these definitions is fundamental to biogeography and conservation biology.

Pair 1 is correctly matched: Flora refers to the collective plant life occurring in a particular region, habitat, or geological period. It encompasses all indigenous native plant life of a specific area.
Pair 2 is correctly matched: Fauna refers to the collective animal life found in a particular region or time period.
Pair 3 is incorrectly matched: Endemic species are those found exclusively in a specific geographical area and nowhere else in the world (e.g., the Asiatic Lion in Gir Forest). Species that are found almost everywhere are termed Cosmopolitan species.
Pair 4 is incorrectly matched: Extinct species are those that no longer exist anywhere on Earth (e.g., the Dodo). Species whose numbers are diminishing and are at risk of extinction are classified as Endangered or Threatened.

Key Takeaway: Endemism denotes strict geographical restriction to a specific locale, whereas extinction signifies the complete and irreversible disappearance of a species globally.
