1. What aspects are important for the success of biological pest control? 2. Why is this organism considered a pest? How has it affected other populations?
3. What do you think would have happened to the populations of their prey if this plague were not present? Explain your answer.
4. How the species proposed for the biological control of the pest could be a limiting factor for the pest population? Explain.
5. What other factors could limit the pest population and help control it?

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
