    Ecologists use the birth and death rates to calculate a population's growth rate, the rate the population is changing. The birth rate (b) minus the death rate (d) equals the growth rate (g). So, B-D=G  Based on this formula: a population of rabbits with an average of 760 births and 227 deaths has a growth rate of _________ per year:

    • 533 rabbits

    • 233 rabbits

    • 227 rabbits

    • 987 rabbits
