Which stage of cultural eutrophication occurs last? 

A)  algae blooms 
B)  increase in aerobic bacteria 
C)  fish kills 
D)  increase in anaerobic bacteria

Cultural Eutrophication

The process by which a body of water becomes overly enriched with minerals and nutrients, often due to runoff from the land, leading to excessive growth of algae and decline in water quality.

Algae Blooms

Rapid increase or accumulation in the population of algae in water systems, often resulting in discoloration of waters and causing negative ecological effects.

Anaerobic Bacteria

Microorganisms that thrive in environments lacking oxygen and can break down substances in the absence of air, often used in waste treatment processes.
