Key differences, features, and comparative analysis of 4. Growth Models — Exponential (J) and Logistic (S).
| Feature | Exponential Growth | Logistic Growth |
|---|---|---|
| Resources | Unlimited | Limited |
| Equation | dN/dt = rN | dN/dt = rN[(K − N)/K] |
| Integral form | Nt = N0ert | — |
| Curve shape | J-shaped | S-shaped / sigmoid |
| Phases | Continuous acceleration | Lag → Acceleration → Deceleration → Asymptote |
| Carrying capacity | Not considered | K is central |
| Competition | Absent | Present |
| Also called | Geometric growth | Verhulst–Pearl growth |
| Realism | Unrealistic long-term | More realistic (resources are finite) |
