Describe what each type of survivorship show (type1, type2, and type3)

There are three types of survivorships:

Type 1: Type 1 survivorship includes organisms which have high chances of surviving through the early and middle stages of life. Their population tends to decline in the old age. For example, humans

Type 2: Type 2 survivorship contains organisms which have a constant mortality rate. The chances of an individual to die are independent of their age. For example, birds

Type 3: Type 3 survivorship includes organisms which have a rapid death rate during the early stages and only a few organisms survive till adulthood.
