The expression P(t + 1) represents the number of rabbits living in a national park one month after month t, which is essentially the rabbit population in the (t + 1)-th month.
The expression P(t + 1) represents the number of rabbits living in a national park in the month following month t. Specifically, if t is the current month, then t + 1 is the next month. Answer choice B correctly defines P(t + 1) as representing the rabbit population in the (t + 1)th month.
This is in line with conventional notation in population dynamics where P(t) signifies the population at time t. Therefore, P(t + 1) shifts the focus by one time unit, providing the population count for the subsequent month.
It is important to note that P(t + 1) is not the initial population, the average population, or the difference in population, but simply the population at a later time.
Understanding this notation is crucial when working with models of population growth like the exponential model P = Poer(t-to) or in assessing the carrying capacity of an ecosystem, represented as Q in ecological equations.
