The life table (above, left) lists the number of survivors remaining each year out of a cohort of 1000 yellow-eyed penguins that hatched at the
same time. Plot a survivorship curve using this data; clearly and completely label your x and y axes and give this graph a descriptive name.
1. Based on the 3 general types of survivorship curves, which one does this example best fit?
2. Reproduction typically begins in Year 3 of the penguin's life. What percent of the original 1000 penguins survived to reproduce? To reach
age 15?
