Sam and his Dad were trying to combat the fire ants in the backyard. They tried several brands of fire ant "killing" chemicals but none worked. Finally, Sam's Dad decided to try an old-time idea: pouring grits on the mounds. What question could be used to guide Sam's study of fire ants?
A) Why is it so difficult to kill fire ants?
B) If grits are poured in a fire ant mound, then the ants will die.
C) Do grits work better at killing fire ants than commercial products?
D) Will ants eat grits and die when grits are poured in a fire ant mound?

Explanation:

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.
