← HistoryWhich consequence results when the Aztec's floating chinampa system loses hydraulic connectivity?
A)Increased soil microbial activity
B)Nutrient depletion stagnates plant growth✓
C)Diminished evaporative cooling occurs
D)Proliferation of nitrogen fixing bacteria
💡 Explanation
Nutrient depletion occurs because the canals facilitate nutrient exchange through hydraulic action; therefore, without circulation, nutrient replenishment from sediment decay stalls, rather than benefiting from microbial activity, limiting crop productivity.
