Read the paragraph and answer the Question given below:

There is no natural habitat on earth known that is inhabited just by a single species. For any species, the minimal requirement is one more species on which it can feed. Even a plant species, which makes its own food, cannot survive alone and needs soil microbes to break down the organic matter in soil and return the inorganic nutrients for absorption. It is obvious that in nature, animals, plants and microbes do not and cannot live in isolation but interact in various ways to form a biological community.

Which of the following is not associated with realistic growth model?

J-shaped growth curve

The correct answer is Option (2) → J-shaped growth curve

Logistic growth : Logistic growth is a population growth model that describes a population initially growing exponentially but eventually reaching a carrying capacity and stabilizing.The carrying capacity represents the maximum population size that the environment can sustain with its available resources. 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. The Verhulst-Pearl logistic growth model is another term for logistic growth.

Exponential 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.Resource (food and space) availability is  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.

Population growth curve a when responses are not limiting the growth, plot is exponential, b when responses are limiting the growth, plot is logistic, K is carrying capacity
