Which outcome arises from the presence of decaying organic matter within a pre-Columbian chinampa system?

💡 Explanation

When organic matter decays within the oxygen-poor confines of a chinampa, anaerobic decomposition occurs because methanogenic archaea consume organic carbon. Therefore methane gas production increases, rather than decreased nitrogen fixation, increased salinity, or decreased phosphorus availability which would need different conditions.
