The P680+ molecule is the strongest known biological oxidizing agent. Based on what you know about its function in PSII, why is this a necessary feature of P680+? P680+ obtains electrons from the oxygen atom in a water molecule, so it must have a stronger attraction for electrons than oxygen has. P680+ is the molecule that transfers electrons to plastoquinone (Pq) of the electron transfer system. P680+ transfers its electrons to reduce NADP+ to NADPH. P680+ is the receptor for the most excited electron in either photosystem of photosynthesis.

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.
