Question: A population of small fish lives in a lake with a sandy bottom. Large shore birds prey on these fish. Although most of the fish are the same light brown color as the sandy lake bottom, about 10% are mottled. A construction company begins dumping loads of gravel in the bottom of the lake, giving it a mottled appearance. Which outcome would you predict? Need Assignment Help?
