A common ancestor

Three types of rabbits (dark brown fur, light brown fur, and white fur) live in a meadow amongst tall grasses they fed on. A drought hit and a lot of the grasses died leaving just the soil and some plants. What change in the rabbit population would you expect? (Jot down thoughts to discuss)
White rabbits would decline rapidly being exposed to predators. Brown rabbits would decline slightly due to food shortage but be able to survive better.

If another volcanic eruption occurred and the soil changed to volcanic rock like in location B, what would you expect to change in the mouse population at location A?
The darker mice would survive to reproduce as they are more suited to the new environment. The white mice population would go down.
