Mathematics Education is Undetermined,al ecologists, such as Richards (1940), had expressed their results showing the successive reductions in the population of an insect throughout a single generation, Deevey (1947) was really the first to focus attention on the importance of this approach. Life-tables have long been used by actuaries

An Invitation to Mathematical Biologyen most widely applied with vertebrate populations. Analysis is easiest with two extreme types of population — the stationary and the expanding. If the population can be assumed to be stationary, then the fall-off in numbers in successive age groups will reflect the survivorship curve and thus a tim
