| List-I | List-II |
|---|---|
| Terms | Relationships |
| (A) Natality | (I) Number of individuals of the same species that have come into the habitat from elsewhere during the given time |
| (B) Verhulst-Pearl logistic growth | (II) Number of individuals of the population who left the habitat and gone elsewhere during the given time |
| (C) Immigration | (III) Number of births during a given period in the population |
| (D) Emigration | (IV) Sigmoid curve |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
(A) Natality — this matches (III) Number of births during a given period in the population. Natality is the birth rate. It adds individuals to the population.
(B) Verhulst-Pearl logistic growth — this matches (IV) Sigmoid curve. When resources are limited, growth is slow at first, then fast, and then it levels off at the carrying capacity. This gives an S-shaped curve.
(C) Immigration — this matches (I) Number of individuals of the same species that have come into the habitat from elsewhere during the given time. Immigration adds individuals to the population.
(D) Emigration — this matches (II) Number of individuals of the population who left the habitat and gone elsewhere during the given time. Emigration removes individuals from the population.
Note: A similar question was also asked in CUET (UG) 2026 on 14-05-2026 (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.”
Population Growth – “… A population growing in a habitat with limited resources show initially a lag phase, followed by phases of acceleration and deceleration and finally an asymptote, when the population density reaches the carrying capacity. A plot of N in relation to time (t) results in a sigmoid curve.”
