What type of population growth curve is characterized by an initial lag phase, rapid exponential acceleration, and deceleration as the population approaches carrying capacity?

Answer and explanation

Correct answer: C. sigmoid logistic growth curve

  1. Step 1: Logistic growth starts slowly (lag phase), enters rapid exponential growth (log phase), and levels off asymptotically at carrying capacity (stationary phase), forming an S-shaped (sigmoid) curve. Answer: sigmoid (S-shaped) logistic growth curve. Why not the others: J-shaped curves experience exponential growth followed by sudden population crashes; linear growth adds constant absolute numbers.
