Describe Growth `"Models"//"Curves."`

Explanation

Populations show characteristic growth patterns or forms. These patterns can be plotted and termed as J-shaped growth form and S-shaped growth from (Sigmoid from).
i. J shaped growth from : When a populataion increases rapidly in an exponential fashion and then stops abruptly due to environmental resistance or due to sudden appearance of a limiting factor, they are said to exibit J-shaped growth from. Many insects show explosive increase in number during the rainy season followed by their disapperance at the end of the season.
ii. S-Shaped growth form (sigmoid growth) : Some populations, as in a population of small mammals, increase slowly at first then more rapidly and gradually slow down as enviromental resistance increases where by equilirium is reached and maintained. Their growth is represented by S shaped growth curve.
