← HistoryWhich consequence results when excessive nutrients leach from Incan terrace farms?
A)Increased downstream aquatic biomass✓
B)Soil erosion up-slope accelerates
C)Decreased crop drought resilience
D)Reduced nitrogen fixation rates
💡 Explanation
Increased downstream aquatic biomass results because agricultural runoff leads to nutrient enrichment, triggering algal blooms via eutrophication. These blooms reduce oxygen levels; therefore, biomass increases due to algal production, rather than nitrogen depletion or soil degradation.
