According to the provided bar graphs, what combination of environmental conditions and mouse characteristics resulted in the highest number of mice being caught by owls?

  • A: Light-colored soil, full moon, dark coat mouse.
  • B: Dark-colored soil, full moon, light coat mouse.
  • C: Light-colored soil, no moon, dark coat mouse.
  • D: Dark-colored soil, no moon, light coat mouse.

Explanation

To find the highest number of mice caught, we need to compare all bars across both graphs. In Graph A light-colored soil , the 'Dark coat' bar under 'No moon' shows approximately 37 mice caught. This is the highest value across both graphs. This scenario represents poor camouflage for the dark mouse against light soil when there is no moonlight to obscure vision.
