Mrs. Strunk's Earth Science class used an erosion model to investigate the relationship between the slope of a hill, or incline, and
the amount of soil that washes off of the incline.
The class increased the slope of the incline from 1 to 5. Then, they poured 100 ml of water down the incline. Finally, they
collected the soil from a tray at the bottom of the incline, dried the soil in an oven, and used a balance to find the mass of the soil.
The data from their study is shown below.

Based on the graph, more soil is washed away when
A. the slope of the incline is less steep.
B. the soil is made mostly of sand.
C.
the slope of the incline is steeper.
D.
there are fewer rocks in the soil.

your answer is c

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.
