One year ago, what limiting factor was the most influential in determining carrying capacity?

Explanation:

Limiting factors include a low food supply and lack of space to live in. Limiting factors can lower birth rates, increase death rates, or lead to emigration because of infertile land which is  will unable you to grow your own plants. When organisms face limiting factors, they show logistic growth

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.
