True or False? a) In Lotka-Volterra competition models, coexistence CANNOT occur if interspecific competition is stronger than intraspecific competition. b)There are three types of survivorship curves that describe mortality rates at different age classes. A type I survivorship curve describes a population with low juvenile mortality, while a type III survivorship curve describes a population with high juvenile mortality.

For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.
