← HistoryWhich consequence arises in pre-Columbian chinampa agriculture nearing winter?
A)Increased frost susceptibility of maize✓
B)Enhanced nitrogen fixation within soil
C)Decreased amphibian biodiversity overall
D)Reduced evapotranspiration from maize.

Lower temperatures during the fall decrease enzymatic activity, because the metabolism that generates defensive compounds shuts down. Therefore, maize stalks become more delicate to handle due to reduced cryoprotection, rather than benefiting from reduced transpiration.
