Distinguish between exponential and logistic population growth, and give the equation for each.
Original Khojo Papers practice question — not from a past board paper.
Answer
Exponential growth assumes unlimited resources and gives a J-shaped curve, dN/dt = rN. Logistic growth allows for a carrying capacity K and gives a sigmoid curve, dN/dt = rN(K − N)/K, in which growth slows as the population approaches K.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
No natural population can grow exponentially for long, because resources are always finite.
