Question

What is the correct sequential order of phases in an S-shaped or sigmoid (logistic) growth curve?

Options

• Stationary Phase → Log Phase → Lag Phase

• Log Phase → Lag Phase → Stationary Phase

• Lag Phase → Stationary Phase → Log Phase

• Lag Phase → Log Phase → Stationary Phase

Answer 1

Logistic growth follows three sequential phases: Lag Phase, Log Phase, and Stationary Phase. The population first adapts, then grows rapidly, and finally stabilises.
