Final answer:
Type I survivorship curves represent low mortality in older individuals. Type II survivorship curves show relatively constant mortality throughout the lifespan. Type III survivorship curves have high early age mortality and lower mortality in advanced years.
Step-by-step explanation:
Type I survivorship curves represent low mortality in the early and middle years and primarily in older individuals. These organisms produce few offspring and provide good care to them. Examples include humans and most mammals.
Type II survivorship curves show relatively constant mortality throughout the entire lifespan. Death is equally likely to occur at any point. Many bird populations exhibit this type of survivorship curve.
Type III survivorship curves indicate high mortality in early ages, and lower mortality rates for organisms that reach advanced years. These organisms typically produce large numbers of offspring but provide little or no parental care. Examples include trees and marine invertebrates.
