Which outcome results from reduced water circulation within Aztec chinampa systems?

💡 Explanation

Impaired nutrient replenishment occurs because limited water flow reduces convective transport, a mass transfer mechanism, decreasing the delivery of decomposed organic matter. Therefore fertility reduces, rather than options like altered precipitation or sediment settling rates, are the issue.
