Tilman's experiments showed that increasing species richness enhanced the stability of plant production in the plots because
A) it increased the stability of each species' performance.
B) it increased the likelihood of predation.
C) it made the community more attractive to immigrating species.
D) as species richness increased, more nutrients remained in the soil.
E) different species performed better during drought years and wet years.
