What are the functions of the cardiovascular system?

The cardiovascular system has five parts:

Arteries- carry oxygen blood away from the heart to the body and form the circulatory system.

Capillaries- carry blood to the skin and other tissues.

Veins- return blood to the heart from the rest of the body.

Heart- pumps blood throughout the body.

Blood- carries oxygen to cells, waste away from cells, disease-fighting cells, regulates pH levels and regulates body temperature.

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.
