Answer:
Step-by-step explanation:
A. To calculate r, we need to use the formula r = (b-d)/N, where b is the number of births, d is the number of deaths, and N is the population size.
r = (240-170)/500
r = 0.14
Since r is positive, this population is experiencing exponential growth.
B. To calculate the number of individuals at the start of the second generation, we need to use the formula Nt = N0e^(rt), where Nt is the population size at time t, N0 is the initial population size, e is the base of the natural logarithm, r is the per capita growth rate, and t is the number of time intervals.
For the first generation, t = 1, so:
N1 = 500e^(0.14*1)
N1 = 575
Therefore, there will be 575 individuals at the start of the second generation.
C. To calculate the number of individuals at the start of the third generation, we need to use the same formula, but with t = 2:
N2 = 500e^(0.14*2)
N2 = 659
Therefore, there will be 659 individuals at the start of the third generation.
