← HistoryWhich farming benefit arises when drought reduces chinampa canal water in Aztec maize cultivation?
A)Increased disease resistance via osmotic pressure
B)Accelerated maturity from water stress hormones
C)Concentrated nutrients enhancing soil fertility✓
D)Reduced pest populations due to habitat loss
💡 Explanation
When drought reduces canal water, capillary action concentrates dissolved nutrients from the sediment (muck) at the surface because water evaporation deposits materials. Therefore, soil fertility increases benefiting maize, rather than enhanced disease resistance or accelerated maturity, which typically demand specific biochemistry under differing conditions.
