Question

The initial values for the fog beetle population are as follows:

Initial # of fog beetles (N0) = 2,000,
birth rate=.88 (b)
death rate= .05 (d)

What is the calculated population growth rate (r) for the beetles?
Growth Rate(r) = birth rate (b)- death rate (d)

.88

.05

.83

.94

Answer 1

Answer: 0.83 (=0.88-0.05)

Growth rate is the speed/rate at which the number of individuals within a population increases.

As the current growth rate of the fog beetles is 83%, the population will increase with 1660 individuals per reproductive cycle (N=N0*r --> N=2000*0,83 --> N=1660).
