Question

Exponential growth occurs when there is

• A. A great environmental resistance
• B. No environmental resistance
• C. No biotic potential
• D. A fixed carrying capacity

Answer 1

The correct option is B No environmental resistance

A population can have two types of growth curves SS shaped and JJ shaped. There is an initial phase of slow growth called lag phase.it is followed by phase of rapid growth called exponential growth or lag phase. In SS shaped or sigmoid growth curve, there is a point of inflections where after growth slows down and reaches a plateau an equilibrium or stagnant phase. When resources are unlimited, populations exhibit exponential growth, resulting in a JJ-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce. It levels off when the carrying capacity of the environment is reached, resulting in an SS-shaped curve.

So, the correct answer is 'No environmental resistance'.
