图8. 化学计量内稳性理论的示意图。A, 生物体中的元素比率随环境中元素比率的变化呈现协同变化, 无内稳性。B, 生物体中的元素比率随环境中元素比率的变化而不变, 呈现出严格的内稳性。图引自Sterner和Elser (
Fig. 8. Schematic diagram of Stoichiometric Homeostasis Theory. A shows the coordinated variation of organism vs environment nutrient ratios (i.e. no stoichiometric homeostasis). B shows that organism nutrient ratios keep stable with the changing environment nutrient ratios (i.e. strict stoichiometric homeostasis). This figure is replotted from Sterner & Elser (
