For a population that grows exponentially in the time interval (t, t + 1), we have N t+1 = R N t , where N denotes population size and R denotes the growth rate. Under intraspecific competition where births and deaths are density-dependent, we expect the population to stabilize at carrying capacity, K. If N t /N t+1 is plotted as a linear function of N t , and we denote (R-1)/K as 'a', which of the following is the correct relationship that describes population growth?
