    Ms. Lobb's period 5 class from Hudson Falls Middle School, Hudson Falls, New
    York answers:
    Upwelling is the movement of deeper, cooler and often nutrient-rich
    layers of ocean water to the surface. Whales eat at the surface of the
    water so if the fish and krill go up for nutrients, the whales would get
    more food.
