Detailed explanation-1: -Survivorship curves are graphs that show what fraction of a population survives from one age to the next.
Detailed explanation-2: -A type II survivorship curve shows a roughly constant mortality rate for the species through its entire life. This means that the individual’s chance of dying is independent of their age. Type II survivorship curves are plotted as a diagonal line going downward on a graph.
Detailed explanation-3: -In survivorship curve. The Type III curve, characteristic of small mammals, fishes, and invertebrates, is the opposite: it describes organisms with a high death rate (or low survivorship rate) immediately following birth.
Detailed explanation-4: -Type I or convex curves are characterized by high age-specific survival probability in early and middle life, followed by a rapid decline in survival in later life.
