Help me please I am really stuck on this question and it it is due in a hour please help

The light mice are more visible to the predator, so they are eaten. The dark mice blend in with their environment, making it harder for the predator to see them. As a result the light mice are eaten, while the dark mice remain hidden from the predators sight

In natural selection, the species with the most advantageous traits gained from adaptation will be more likely to survive. In that particular terrain, the darker mice would be more likely to survive because they blend in more with their environment. The lighter ones pop out more, so the owl is going to go for them the most because he/she/they will probably notice them first. If the owl eats more of the lighter ones, the darker ones will be more populous.

Explanation:

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
