← HistoryWhich outcome resulted when Mesoamerican farmers cultivated maize in chinampas with high water tables?
A)Increased susceptibility to fungal diseases✓
B)Reduced nitrogen fixation in the soil
C)Enhanced phosphorus uptake by the roots
D)Decreased resistance to drought conditions
💡 Explanation
When maize is cultivated in chinampas with high water tables, waterlogging occurs which elevates humidity and reduces oxygen availability, fostering conditions favorable for fungal diseases like blight to proliferate. Therefore, increased susceptibility to fungal diseases results, rather than altered nitrogen, phosphorus, or drought resistance that depend on different environmental pressures.
