    Population of dice mice after one year = 2000

    Population of wood rats after one year = 1000

    The population of deer mice is growing faster than the popular of wood rats

    Step-by-step explanation:

    The expression for population = dN/dt = rN

    Upon integration N = rN²/2

    Therefore for population N = 200 and r = 0.1

    N after one year = (0.1 x 200²) / 2 = 2000

    Therefore for population N = 100 and r = 0.2

    N after one year = (0.2 x 100²) / 2 = 1000

    Hence the population of deer mice is growing faster than the popular of wood rats
