Match List-I with List-II
| List-I Terms | List-II Features |
|---|---|
| (A) Natality | (I) Exit of individuals |
| (B) Mortality | (II) Entry of individuals |
| (C) Immigration | (III) Death rate |
| (D) Emigration | (IV) Birth rate |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
(A) Natality — this matches (IV) Birth rate. Natality is the number of births in a population in a given period. Births add individuals, so the population density goes up.
(B) Mortality — this matches (III) Death rate. Mortality is the number of deaths in a population in a given period. Deaths remove individuals, so the density goes down.
(C) Immigration — this matches (II) Entry of individuals. Immigration is the number of individuals of the same species that come into the habitat from elsewhere in a given time.
(D) Emigration — this matches (I) Exit of individuals. Emigration is the number of individuals that leave the habitat and go elsewhere in a given time.
Note: A similar question was also asked in CUET (UG) 2025 on 22-05-2025 (Slot 2).
