Q.Describe Growth Models/Curves.

Step 1. Populations show characteristic growth patterns that can be plotted and classified into two named forms: J-shaped and S-shaped (sigmoid).

Step 2. The J-shaped growth form describes a population increasing rapidly in an exponential fashion that then stops abruptly, due to environmental resistance or the sudden appearance of a limiting factor — many insect populations follow this pattern during the rainy season, then disappear at season's end.

Step 3. The S-shaped growth form describes populations, such as small mammals, that increase slowly at first, then more rapidly, and then gradually slow down as environmental resistance increases, until equilibrium is reached and maintained. …

Name both growth curves, describe their shape and termination behaviour, and define the shared underlying terms (biotic pot …
