History

In Aztec chinampa agriculture, which outcome results from eutrophication?

A)Algal blooms deplete dissolved oxygen
B)Soil erosion increases land stability
C)Nutrient uptake becomes phosphorus-limited
D)Saltwater intrusion decreases soil salinity

💡 Explanation

Eutrophication causes excessive nutrient enrichment, triggering rapid algae growth; this algal bloom consumes available oxygen via decomposition, causing aquatic dead zones; therefore oxygen depleted conditions occur, rather than creating preferable growing conditions.
