Major predictors of microbial metabolic efficiency. (A) Based on the percentage increase in mean squared error (%IncMSE) from the random forest analysis. (B) Spearman correlation analysis of microbial carbon metabolism indicators with selected biotic and abiotic factors. Enzyme/MBC is calculated by normalizing the activity to units/mg MBC and represents the specific enzyme activity. *p < 0.05, **p < 0.01, ***p < 0.001.
