Rainforest

Explanation:

Sunlight is a major limiting factor in the rainforest due to a very dense canopy created by taller trees and thus sunlight is blocked from reaching the rainforest floor making underbrush growth sparse.  In rainforest, plant growth is confined to the surface due to limitations of light penetration as light intensity decreases with depth.

youre right there are

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.
