E) increase in anaerobic bacteria

Question

Quizplus · Accepted Answer

Increase in anaerobic bacteria is the final stage of cultural eutrophication. When oxygen is depleted due to the decomposition of organic matter, anaerobic bacteria thrive and produce harmful gases such as methane and hydrogen sulfide, leading to the death of aquatic life. Fish kills (A), blooms of algae (B), increase in aerobic bacteria (C), and increase of plants such as duckweed (D) occur earlier in the process.
