Using the survivorship curve below, describe how the likelihood of death varies with age between Type I, II, and III organisms. Type I: Offspring, in their younger years, have a HIGH rate of survival. LARGE numbers of these organisms live into old age. Type II: There is equal death among each age interval. Type III: Offspring, in their younger years, have a LOW rate of survival. SMALL numbers of these organisms live into old age.
