The primary function of stems is to
a.) carry out photosynthesis
b.) store food
c.) support the leaves

C. support the leaves

Explanation:

without the stem the plants wouldnt receive any water or minerals, its like the tube of an instrument some instruments require air to make music so plants also with out the tube (stem) how are they going to receive life?...they would just die and plus a plant HAS to have a stem (does it?yes, yes it does)

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.
