Which benefit resulted from the Aztec chinampa system's saturated soil layers?

💡 Explanation

When Aztec chinampas kept soil saturated, capillary action maintains high soil water content and reduces the vapor pressure deficit near plant stomata, minimizing transpiration losses. Therefore minimized water loss results, rather than reduced need for nitrogen, enhanced phosphorus absorption, or pest resistance, which rely different mechanisms.
