QUESTION 3: Life tables and survivorship The data below represent a cohort of organism "X", tracked from birth to death. Deaths during Number alive at start of period Proportion surviving at start of time interval 432 1.00 42 0.10 13 11 10 "5-6" 9 "6-7" 7 "7-8" 3 "8-9" 0 * Numbers are reported over eight equal sized time periods - these could represent days, weeks, months or years. Time period* "0-1" "1-2" "2-3" "3-4" "4-5" period 390 29 iii. Rate of mortality during time period 0.90 0.69 a) Complete the table by recording survivorship (proportion alive at the start of the time period), the number of deaths and the mortality rate for each time period. For each column you need to ensure you indicate how you performed your calculation (e.g. show one example calculation or provide a formula). Based on these data, suggest an organism which species X might represent, explaining your logic.
