Question

The graph shows two types of population growth curve. A is exponential and B is logistic.
Which one of the following growth model considered as more realistic one?

• A. Exponential growth curve
• B. Logistic growth curve
• C. Both the growth curves
• D. None of the above

Answer 1

The correct option is B Logistic growth curve

• The growth of animals in a population depends on the available resources in the environments.
• This model applies to the population depends on density-dependent factors like food abundance, resting place, sickness, competition, etc. It says that the growth of the population depends on environmental factors.
• In contrast, the exponential growth does not consider the environmental limits, it says a population can grow with no limits. So, the logistic growth curve is more realistic.
  Hence, the correct option is B.
