Which factor decreases the rate of a chemical reaction? a. an inhibitor b. a co-factor c. increased substrate

A. an inhibitor

An enzyme inhibitor is a substance that slows down the action of the enzyme by binding at the active site of the enzyme preventing the binding of the substrate to it. It alters the catalytic activity of the enzyme either by slowing down or simply stopping the catalytic 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.
