Q54 / 200 · MHT CET - Medical 2026 (25 April Shift 2) · Biology
Which of the following depicts Exponential growth curve of a population?
- A
- B
- C
- Correct answerD
Solution
Exponential growth occurs when resources in a habitat are unlimited. In this type of growth, the population size increases continuously at an accelerating rate, resulting in a J-shaped curve.
The equation for exponential growth is $\dfrac{dN}{dt} = rN$, where $N$ is the population size, $r$ is the intrinsic rate of natural increase, and $t$ is time.
The graph in the fourth option clearly shows a J-shaped curve, which represents exponential growth. The first option shows an S-shaped (sigmoid) curve, which represents logistic growth.
Answer:
