Zoology - Organisms and Populations Question with Solution | TestHub
Given below are two statements : one is labelled asAssertion Aand the other is labelled asReason R.
Assertion A :The logistic growth model of populations is considered more realistic than the exponential growth model.
Reason R :Resources are finite.
In the light of the above statements, choose themost appropriateanswer from the options given below :NEET 2026 (Re-NEET)
Options:
Answer:
Solution:
The exponential growth model assumes that resources are unlimited, which allows a population to grow continuously at a constant rate. However, in nature, resources such as food, space, and water are finite and eventually become limiting factors for population growth.
The logistic growth model incorporates these limiting factors and introduces the concept of carrying capacity, which is the maximum population size that an environment can sustain indefinitely. Because it accounts for the finite nature of resources, the logistic growth model is considered more realistic for most animal populations.
Therefore, both Assertion A and Reason R are correct, and Reason R is the correct explanation of Assertion A.
Answer: Both and are correct and is the correct explanation of
