Q200 / 200 · NEET 2023 (All India) · Zoology

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
  • Correct answer
    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

Solution

  • When there is limited resources available, in nature, there is sheer competition and only the fittest can survive. This indicates a logistic growth curve in the population.
  • If there are unlimited resources, the chances of competitions are rather less. This leads to exponential growth of the population.
  • In expanding age pyramid of a population, the percent individuals of pre-reproductive age is largest followed by reproductive and post reproductive age groups.
  • Conversely, in a stable population, the percent individuals of pre-reproductives and reproductive age group are nearly the same.

Hence, the correct answer is option: 'B'.
