Explanation:
Detailed explanation-1: -A logistic growth curve is an S-shaped (sigmoidal) curve that can be used to model functions that increase gradually at first, more rapidly in the middle growth period, and slowly at the end, leveling off at a maximum value after some period of time.
Detailed explanation-2: -In logistic growth, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
Detailed explanation-3: -S-shaped or sigmoid growth curve graph indicates that the population growth of a species has three phases-the exponential phase, the transitional phase and the plateau phase.
