What is the logistic growth equation
Options
- AdN/dt = rN
- BdN/dt = rK - N
- CdN/dt = rN(1 - N/K)
- DdN/dt = bN - dN
Correct answer
C. dN/dt = rN(1 - N/K)
Step-by-step solution
A population growing in a habitat with limited resources shows initially a lag phase, followed by phases of acceleration and deceleration and finally an asymptote, when the population density reaches the carrying capacity. A plot of N in relation to time (t) results in a sigmoid curve. This type of population growth is called Verhulst-Pearl Logistic Growth (Figure 11.3) and is described by the following equation: dN/dt = rN(1-N/K) Where N = Population density at time tr = Intrinsic rate of natural increaseK = Carry
