# What does the population growth model equation mean? dN/dt=rN

##### 1 Answer

The equation

#### Explanation:

This is a rather simple and impractical equation because it signifies an Exponential Population Growth. If you are familiar to the Future Value of a compounded interest rate,

dN/dt = rN : a differential equation describing the population growth

where N is the population size, r is the growth rate, and t is time.

N as the population size, r is growth rate, K is carrying capacity.

This equation forces, populations to converge to the carrying capacity. The speed at which the populations approach K is related to the growth rate r.
