NEETZoologyOrganisms and Populations
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The Verhulst-Pearl logistic growth model is considered a more realistic description of population growth in nature than the exponential model. Reason (R): In natural habitats, resources for most animal populations are infinite and never become limiting. In the light of the above statements, choose
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Correct answer
C. (A) is true but (R) is false
Step-by-step solution
According to NCERT, the Verhulst-Pearl logistic growth model is considered a more realistic description of population growth in nature. This is because resources for growth for most animal populations are finite and become limiting sooner or later, leading to competition between individuals for limited resources. Therefore, the Assertion is true but the Reason is false, as it incorrectly states that resources are infinite. Answer: (A) is true but (R) is false
