Chapter 2 · Question 3
Explain endangered, vulnerable, rare, endemic, and extinct species.
Answer
Direct Answer
Endangered species face serious danger of extinction. Vulnerable species may become endangered if harmful factors continue. Rare species have small populations. Endemic species are found only in a particular region. Extinct species no longer exist in the area or on Earth.
Simple Explanation
Endangered species are near extinction. Vulnerable ones may become endangered. Rare species have small populations. Endemic species exist only in one region. Extinct species no longer exist.
Exam-Ready Structure
Species are classified into categories based on their population status and risk of extinction:
• Endangered species: Species that face a very high risk of extinction in the near future if the causes of their decline continue. Their population is critically low. Examples from India: Indian rhinoceros, Asiatic lion, Bengal tiger.
• Vulnerable species: Species that are likely to become endangered if the factors threatening their survival are not controlled. Their population is declining but not yet critically low.
• Rare species: Species with naturally small populations. They may not be currently threatened, but their small numbers make them vulnerable to environmental changes.
• Endemic species: Species found only in a specific geographical area and nowhere else in the world. They are especially vulnerable because any threat to that region threatens the entire species. Example: Nilgiri tahr is endemic to the Western Ghats.
• Extinct species: Species that no longer exist anywhere in the wild or on Earth. Example: the Asiatic cheetah is considered extinct in India, and the dodo is globally extinct.
Key Points
- Endangered species face serious danger of extinction.
- Vulnerable species may become endangered if harmful factors continue.
- Rare species have small populations.

Use the category table to keep the textbook definitions separate and exam-ready.
This is most useful when explaining how endangered and vulnerable species differ.
Use the textbook categories to distinguish endangered, vulnerable, rare, endemic, and extinct species without mixing their meanings.
