Difference equations

  1. Dec 2, 2007 #1
    Consider an annual plant which germinates in the spring, blooms in the summer and produces (on
    average) S seeds in the autumn. A fraction 'a' of the seeds survive the winter. Then a fraction 'b'
    of these germinate the next spring, flower and produce more seeds. Of those that do not germinate,
    again a fraction'a' survive the winter and then a fraction 'c' of these germinate the second spring,
    °ower and produce more seeds. There are no seeds that survive more than two winters.
    (a) Let pn be the plant population in year n. Write the second order difference equation
    satisfied by pn
