NEETZoologyOrganisms and Populations
Read the following statements regarding population growth models: (A) Exponential growth assumes that resources in the habitat are unlimited. (B) The logistic growth curve is J-shaped. (C) Carrying capacity (K) is a feature of the exponential growth model. (D) The logistic growth model is considered more realistic in nature. How many of the above statements are correct?
Options
- AOne
- BThree
- CFour
- DTwo
Correct answer
D. Two
Step-by-step solution
Statement (A) is correct because exponential growth can only occur when resources (food and space) are unlimited, allowing the population to realize its full innate potential to grow in number. Statement (B) is incorrect because the logistic growth curve is sigmoid (S-shaped), whereas the exponential growth curve is J-shaped. Statement (C) is incorrect because carrying capacity (K) is a parameter of the logistic growth model, representing the maximum sustainable population size in a given habitat. Statement (D) is
