Comment on the growth curve given below.

Answers (1)

The growth curve in this figure shows logistic growth of population. We know that resources are limited in nature, and they cannot support unlimited growth in population. Limited resources mean tough competition for resources among individuals. Only those survive which are fit to survive in such a condition. This is what happens in a real-life situation.

In the initial phase, the population shows a lag phase, i.e. it grows at a slow pace.

The lag phase is followed by a phase of acceleration, during which population growth is rapid. The acceleration phase is followed by a phase of deceleration, during which population growth slows down.

Finally, a phase comes when population density reaches the carrying capacity. Carrying capacity defines the load limit of nature; in terms of sustaining a particular population density. Once the population density reaches the carrying capacity, it reaches the phase of the asymptote. This is the phase when population beings to show negative growth.
