Instinctive behaviors that are carried out regardless of earlier experience are called behaviors and are a product of an individual's genotype.

Innate

Explanation:

The innate behavior is carried out inside the organism regardless of the previous experiences.

The innate behavior inside a human being or organism is specific to the individuals genotype.

The behavior that is innate inside the individual is limited to the organism and is not a general character which is found in all the organism.

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.
