calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.

144

Explanation:

Population growth rate refers to the measure of how a population (N) changes over a particular time (t). Hence, it is termed as (dN/dt) where d represents the change.

The logistic population growth rate equation is given as:

dN/dT = rmaxN (K-N/K)

Where; dN/dt = population growth rate

K = carrying capacity of

population

rmax = maximum per capital

growth rate

N = population number

dN/dt = 0.3 × 1200 (2000-1200/2000)

dN/dt = 360 (800/2000)

dN/dt = 360 (0.4)

dN/dt = 144

Hence, the growth rate of the population (dN/dt) is 144
