The bars on the graphs show the numbers of mice that were caught, but keep in mind that mice that were not caught by the owl escaped predation.

Question

On a moonlit night, would a dark brown mouse be more likely to escape predation by owls on dark- or light-colored soil? What data support your conclusion?

On dark-colored soil; fewer dark brown mice were caught on dark soil than on light soil under a full moon.
On dark-colored soil; fewer light brown mice than dark brown mice were caught on light soil under no moon.
On light-colored soil; fewer dark brown mice were caught on dark soil than on light soil under a full moon.
On light-colored soil; the lowest level of predation was light brown mice on light soil.

Part F
Is a dark brown mouse on dark-colored soil more likely to escape predation under a full moon or with no moon? What data support your answer?

Under no moon; the owl caught more dark mice when there was no moon (about 20) than when there was a full moon (about 12).
Under no moon; the owl caught more light mice when there was a full moon (about 17) than when there was no moon (about 11).
Under a full moon; the owl caught more dark mice when there was no moon (about 20) than when there was a full moon (about 12).
Under a full moon; the owl caught more dark mice when there was no moon (about 37) than when there was a full moon (about 19).

Answer 1

To answer your questions:

Part E: A dark brown mouse would be more likely to escape predation by owls on dark-colored soil. This conclusion is supported by the data showing that fewer dark brown mice were caught on dark soil compared to light soil under a full moon. This suggests that the dark brown mice have better camouflage on dark soil at night, which helps them avoid predation.

Part F: A dark brown mouse on dark-colored soil is more likely to escape predation under no moon. The supporting data indicates that the owl caught more dark mice when there was no moon (approximately 20) compared to the full moon (approximately 12). This suggests that lower light conditions (no moon) provide a better chance for dark brown mice to evade predation.

Part G: A dark brown mouse would be most likely to escape predation at night on dark-colored soil with no moon. This scenario provides both the advantage of camouflage from the dark soil and the cover of darkness to further reduce the likelihood of being spotted by an owl.
