← HistoryWhich consequence emerged historically when the artificial island infrastructure of Mesoamerican chinampas became oversaturated?
A)Increased nutrient availability for maize
B)Elevated root disease susceptibility in maize✓
C)Improved aeration within the soil
D)Enhanced carbon sequestration in the soil
💡 Explanation
The oversaturation triggered anaerobic conditions restricting oxygen because it promoted proliferation of bacteria, causing root rot disease in maize due to inadequate root respiration; therefore disease increased, rather than the other effects, which need drained soils.
