Match List-I with List-II
| List-I Terms | List-II Explanations |
|---|---|
| (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 during a given period. Births add to the population, so natality raises its density.
(B) Mortality — this matches (III) Death rate. Mortality is the number of deaths in a population during a given period. Deaths remove individuals and lower the density.
(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 during a period.
(D) Emigration — this matches (I) Exit of individuals. Emigration is the number of individuals that leave the habitat and go elsewhere during a period. Natality and immigration increase a population; mortality and emigration decrease it.
Note: A similar question was also asked in CUET (UG) 2025 on 28-05-2025 (Slot 1).
NCERT Extract:
Population Growth – “… (i) Natality refers to the number of births during a given period in the population that are added to the initial density.
(ii) Mortality is the number of deaths in the population during a given period.
(iii) Immigration is the number of individuals of the same species that have come into the habitat from elsewhere during the time period under consideration.
(iv) Emigration is the number of individuals of the population who left the habitat and gone elsewhere during the time period under consideration.”
