Study the population growth curve given below and answer the questions
that follow :
(a) Identify ‘A’ and ‘B’ shown in the graph.
(b) When and why do such curves occur in a population ?
(a) A-Exponential growth
B- Logistic growth
(b) When there are unlimited resources available the population grows
exponentially and if the resources are limited then the population growth will be in limit and this growth is called Logistic growth.
