Consider a colony of beetles. Assume that the beetles live at most 4 years. Divide the female population into four age groups 0-1, 1-2, 2-3, 3-4, each spanning 1 year. Suppose the current number of females is 1 10, spread over the four age groups according to 50:35: 15: 10. Let the average birth rates per beetle of the four age groups be 0, 5, 3, 1 per year. Suppose the average survival probabilities of the four goups are 0.4, 0.2, 0.1 and 0. Predict the population distribution four years from now. 976.64 120.24 37.816 0.98 Determine the distribution which describes the long-term trend in population growth
