Question

In population growth curve, when responses are not limiting the growth, the plot remains:

• A. Exponential
• B. Logistic
• C. Intrinsic
• D. Neutral

Hint:

When resources are unlimited, population growth is exponential; when resources are limited, growth becomes logistic.

Answer 1

The Correct Option is A

Concept:
Population growth depends on availability of resources such as food, space and nutrients.

Step 1: Understand unlimited growth condition.
When resources are not limiting, population increases rapidly. \[ \text{Unlimited resources} \Rightarrow \text{rapid population growth} \]

Step 2: Identify the growth curve.
Under unlimited resource conditions, population follows exponential growth. \[ N_t=N_0e^{rt} \] where, \[ N_t=\text{population at time }t \] \[ N_0=\text{initial population} \] \[ r=\text{growth rate} \]

Step 3: Compare with logistic growth.
Logistic growth occurs when resources become limiting and carrying capacity is reached. \[ \therefore \text{Correct Answer is (A)} \]
