Its maximum population size to remain stable. This indicates that humans typically experience higher death rates in their population at later ages in adulthood (around age 70). There are 3 types of survivorship curves: Type I individuals survive well early in life and generally live many years. Typically, the number of individuals of the population is plotted on the y-axis of the graph and the age of survivorship is plotted on the x-axis of the graph. A community includes interacting populations without their surrounding environment, while an ecosystem includes the surrounding environment. What factors are involved? After the initial drop in the number of individuals surviving in the population, the graph levels off. As a result, they produce comparatively less number of offspring. 5.
