Summary Introduction
Todescribe: The significance of survivorship curve of an original population.
Introduction: Survivorship is the percentage of an original population that survive to a given age. Survivorship curve is a graph that represents the proportion of individuals surviving to each period for a given species or group. It shows a roughly constant mortality rate for the species throughout its entire life.
