← HistoryIn a chinampa system experiencing prolonged drought, which consequence results from the disruption of nutrient cycles?
A)Increased methane production develops
B)Maize bioaccumulation of heavy metals✓
C)Accelerated algae thrive abnormally
D)Nitrate toxicity increases overall

Decreased water flow inhibits decomposition of organic matter causing reduced nutrient availability in chinampas; therefore, maize root uptake via diffusion gradients causes preferential metals uptake rather than essential nutrients because metals become selectively soluble.
