In the first picture, white and black mice have the same number of the species present in the given environment. In the second picture, a bird appears, and only gets or eats the white mice instead of a black mice. Next, the third picture, we can see that the number of white mice are decreasing because the bird only gets the white mice and not the black mice. We can predict that in the end of the diagram white mice will disappears and black mice will remain the same.
