A small population of bacteria is introduced into a flask of fresh nutrient broth and counted hourly.
Curve A best represents which model of population growth and under what conditions?
- A
Logistic growth at carrying capacity
- B
Density-dependent decline
- Ccheck_circle
Exponential growth (dN/dt = rN) under unlimited resources
- D
Allee effect
Explanation
A J-shaped curve with continuous acceleration represents exponential growth, which occurs when resources are not limiting and per-capita rate r is constant.
