Be sure to answer all parts. The net reproductive rate, R0, of a population can be used to predict whether a population will grow or shrink over time. 1fR 0 is greater than 1 then a population is growing; if it is less than 1, the population is shrinking; and if it is equal to one, then the population is at equilibrium. The size of the next generation of...
