biologist A. G. Tansley performed a famous series of studies on two species of bedstraw, a plant that was used to stuff beds. In nature, heath bedstraw grows on peat soil, and slender bedstraw grows on limestone soil. Tansley discovered both species can grow on both types of soil when the other species is absent. He hypothesized competition explains why, in nature, the two species do not coexist. Which experimental approach would best test his competition hypothesis?
