Match List $I$ with List $II$.
| List $I$ | List $II$ |
| $A$. Logistic growth | $I$. Unlimited resource availability condition |
| $B$. Exponential growth | $II$. Limited resource availability condition |
| $C$. Expanding age pyramid | $III$. The percent individuals of pre-reproductive age is largest followed by reproductive and post reproductive age groups |
| $D$. Stable age pyramid | $IV$. The percent individuals of pre-reproductives and reproductive age group are same |
Choose the correct answer from the options given below:
A
A-II, B-IV, C-III, D-I
B
A-II, B-I, C-III, D-IV
C
A-II, B-III, C-I, D-IV
D
A-II, B-IV, C-I, D-III
(NEET-2023)
Solution
Logistic growth occurs when there is limited resource availability condition.
Exponential growth occurs when there is unlimited resource availability condition.
Expanding age pyramid reflects growing population where the percent individuals of pre-reproductive age is largest followed by reproductive and post-reproductive age groups.
Stable age pyramid shows stable population where the percent individuals of pre-reproductive and reproductive age group are same.
