"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."
