High survival rates, but die out with older age, mature slowly, tend to be both predator and prey, mostly endangered, tend to be larger.
Ex: Humans, elephants, and sharks.
Have a lot of offspring, but very few make it to adulthood, mature rapidly, tend to be prey, not really endangered, tend to be smaller
Ex: Insects, bacteria, and rodents
Have great number of offspring and reproduce for most of their lifetime.
Ex: Sea turtles, fish, and oysters
Reproduction occurs pretty early in life, low mortality rate at birth, high rate of surviving to adulthood, death rates increase at old age.
Ex: Humans, elephants, and sheep
Death rate is pretty uniform throughout all variety of ages, typically reach adult stages quickly.
Ex: Rodents and songbirds
