Detailed explanation-1: -Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Detailed explanation-2: -The sigmoid curve of growth is characteristic of most organisms in their natural environment, including plants, as it maintains an equilibrium over a period of time. It has a lag phase (slow initial growth), an exponential phase or a log phase (rapid growth of plant) and a stationary phase (slow or no growth).
Detailed explanation-3: -Yeast grown in ideal conditions in a test tube show a classical S-shaped logistic growth curve. Examples in wild populations include sheep and harbor seals (Figure 3). In both examples, the population size exceeds the carrying capacity for short periods of time and then falls below the carrying capacity afterwards.
