How does water relate to the ability of a living thing to generate energy?
o without the proper balance of water, chemical reactions in cells could not
o water is responsible for the generation of energy in the cell.
the cell is an aqueous environment.

the question isn't that clear in my opinion but anyways. I know water is not responsible for ATP production in cells and some organisms require a moist environment to diffuse oxygen through their cells like newts can take in oxygen through their skin. So I would probably say the incomplete answer -

(Without the proper balance of water, chemical reactions in cells could not)

-is correct.

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.
