Match the Column I with Column II :

A- 1,2 

B- 3,4

The correct answer is Option (3)- A- 1,2  

                                                  B- 3,4

A. Logistic growth - 1. Sigmoid growth, 2. Verhulst-Pearl logistic growth

B. Exponential growth -3.Unlimited growth,4. J-shaped growth

A. Logistic growth - 1. Sigmoid growth: Logistic growth is a population growth model that describes a population initially growing exponentially but eventually reaching a carrying capacity and stabilizing. The shape of the logistic growth curve is sigmoid, which means it starts with slow growth, accelerates, and then levels off as the population approaches the carrying capacity of the environment.

Verhulst-Pearl logistic growth: The Verhulst-Pearl logistic growth model is another term for logistic growth, which was explained in the match with A. Logistic growth.

B. Exponential growth - 4. J-shaped growth: Exponential growth is a population growth model that describes unregulated, rapid growth where the population size increases continuously without any constraints. The shape of the exponential growth curve is J-shaped, as the population size rapidly increases over time.

Unlimited growth - Resource (food and space) availability is obviously essential for the unimpeded growth of a population. Ideally, when resources in the habitat are unlimited, each species has the ability to realize fully its innate potential to grow in number.
