- Why are polyandrous mating systems more rare than polygynous matings?Only males are capable of multiple rounds of reproduction within a single breeding season.Only females care for the young.Females usually experience more intrasexual selection pressure than males.Females usually devote more energy to offspring production and development.

- How is a clumped population distribution beneficial for prey animals?Being a member of a larger group provides protection for each individual from predators.Prey animals rely on each other to acquire food.Prey animals live in small family groups to raise young.Clumped population distributions ensure that at least one member of the population knows how to identify the seasonal migration route.
