how would a dislodged piece of plaque in the cardiovascular system most likely affect an otherwise healthy person?

the right pulmonary artery could become blocked, restricting blood flow to the right lung.
a narrow region of the superior vena cava could become blocked, restricting blood flow to the heart.
a smaller artery in a leg could become blocked, restricting blood flow to capillaries in the leg.
a narrow vein in the brain could become blocked, restricting blood flow to capillaries in the brain.

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.
