Topic 8.5: Eutrophication
Learning Objective: STB-3.F
Explain the environmental effects of excessive use of fertilizers and detergents on aquatic ecosystems.
Essential Knowledge: STB-3.F.1
Eutrophication occurs when a body of water is enriched in nutrients.
Essential Knowledge: STB-3.F.2
The increase in nutrients in eutrophic aquatic environments causes an algal bloom. When the algal bloom dies, microbes digest the algae, along with the oxygen in the water, leading to a decrease in the dissolved oxygen levels in the water. The lack of dissolved oxygen can result in large die-offs of fish and other aquatic organisms.
Essential Knowledge: STB-3.F.3
Hypoxic waterways are those bodies of water that are low in dissolved oxygen.
Essential Knowledge: STB-3.F.4
Compared to eutrophic waterways, oligotrophic waterways have very low amounts of nutrients, stable algae populations, and high dissolved oxygen.
Essential Knowledge: STB-3.F.5
Anthropogenic causes of eutrophication are agricultural runoff and wastewater release.
