Val works as a paleoclimatologist in Alaska. While studying ice core samples, she identifies an increase in the isotopic ratio of oxygen 10,000 years ago. From this discovery, she knows that Earth's temperature at that time was
7. Aside from
temperature, Val can also learn about
from the ice cores. Val's data suggests that she's uncovered a glacial
climate for this time period. During a glacial climate, Val knows, there would have been
sea level, compared to what
she witnesses today.

the answer is trees if i'm not mistaken

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.  

sorry, is there a picture? i do not see any arrows.
