    A Survivorship Curve is the graphical representation of the proportion or the number of individuals surviving at each age for a given group or species

    Types of curves:

    Type I – A convex curve. Most individual live to adulthood with most mortality in old age. eg. humans, elephants,etc

    Type II – A straight line. An individual’s chance of dying is independent of age. eg. small birds and mammals

    Type III – A concave curve. Few individuals live to adulthood, with the chance of dying decreasing with age.eg. oysters, redwood trees,etc
