ANSWER THIS ASAP: Im losing my got-dang mind over this! Can someone PLEASE tell me in scientific natiation, when u move the decimal to the left is it positive( or when u move it to the left its negative?)? And if u move the decimal to the right is it positive(or when u move it to the right its negative?)?

oh I can try my best to help you so it depends on the whole number you can move the decimal to the left or to the right but if the whole number is positive then it would still be positive just have less value when doing it to the left and it would have more value when moving it to the right .so think of it as moving it to the left as dividing/subtracting and moving it to the right as multiplying/adding hope I helped!! :'))

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.
