← HistoryWhich consequence results when hydraulic terracing fails in ancient farming?
A)Reduced nitrogen fixation rates
B)Increased soil erosion downstream✓
C)Amplified pollinator habitat loss
D)Decreased crop disease resistance
💡 Explanation
Increased soil loss transpires because terracing relies on controlled drainage for water management, therefore loss of structural integrity leads to severe erosion downstream, rather than strictly affecting either plant disease which may occur anyway, nitrogen fixation, or habitat, which are of lesser consequence.
