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
Polar bears are listed in red as they are belong to Endangered Species. These species are gonna extincting due to gradual changes by environmental factors.
