From: Litter chemistry explains contrasting feeding preferences of bacteria, fungi, and higher plants

Effects of 18 different litter materials, either undecomposed (left) or after 180 days of decomposition (right), on the growth of selected bacteria (top) and fungi (center) and higher plants (bottom). Growth is expressed as percent difference compared to the controls (Nutrient Broth, and PDA and water for bacteria, fungi and plants, respectively). White and gray bars indicate inhibitory and stimulatory effects, respectively. For each bar, data refer to mean ± standard error of 14, 6 and 6 target species for plants, bacteria and fungi, respectively.
