Explain
below the increase in the number of black squirrels using ideas of natural
selection. write about: variation,
competition, survival and reproduction
.

Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance

There would be one bar shorter than the bar for peaches.
