Match List-I with List-II
| List-I | List-II |
|---|---|
| Term | Explanation |
| (A) Natality | (I) Number of the same species individuals that have come into the habitat |
| (B) Immigration | (II) Number of deaths during a given time in a population |
| (C) Mortality | (III) Number of the same species individuals that have left the habitat |
| (D) Emigration | (IV) Number of births during a given time in a population |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
(A) Natality — this matches (IV) Number of births during a given time in a population. Births are added to the population, so natality raises its density.
(B) Immigration — this matches (I) Number of the same species individuals that have come into the habitat. Individuals arriving from elsewhere also add to the density.
(C) Mortality — this matches (II) Number of deaths during a given time in a population. Deaths remove individuals and lower the density.
(D) Emigration — this matches (III) Number of the same species individuals that have left the habitat. Individuals leaving for elsewhere also lower the density.
Note: A similar question was also asked in CUET (UG) 2026 on 14-05-2026 (Slot 1).
