organsim:

an individual animal, plant, or single-celled life form.

"fish and other organisms have been destroyed over large areas of the creek"

population:

In biology, a population is a number of all the organisms of the same group or species who live in a particular geographical area and are capable of interbreeding.

communtiy:

"the scientific community"

ecosystem:

"the marine ecosystem of the northern Gulf had suffered irreparable damage"

biome:

a large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.

biosphere:

the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

climate change and pollution

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.
