Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason 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 the most appropriate answer from the options given below :
B. Both A and R are correct and R is the correct explanation of A
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 A and R are correct and R is the correct explanation of A
