Is the following case study an r-strategist or a K-strategist?
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. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.
