Observe the population growth curve and answer the questions given below:

(a) State the conditions under which growth curve ‘A’ and growth curve ‘B’ plotted in the graph are possible.
- Growth curve ‘A’ (Exponential growth): Characterized by unrestricted expansion, this growth occurs when resources (food, space, etc.) are abundant and environmental factors do not impede population increase.
- Growth curve ‘B’ (Logistic growth): This curve represents growth under natural, resource-limited conditions. Environmental resistance factors, including competition and predation, reduce the growth rate, eventually stabilizing the population at its carrying capacity.
