displacement reaction.

Explanation:

When chlorine gas is passed through a solution of potassium iodide, as a result of this reaction the products i. e. solid iodine and potassium chloride are formed. This type of reaction is called a displacement reaction because in this reaction the less reactive iodine that is attached with potassium iodide is replaced by the more reactive chlorine molecule so the displacement of atoms held so we called it displacement reaction.

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.
