Eutrophication is defined as the process by which a body of water becomes enriched with nutrients, often leading to an overgrowth of algae and other microorganisms. This overabundance of nutrients typically results from runoff containing fertilizers or sewage.

Supplemental Knowledge

Eutrophication refers to the enrichment of water bodies with nutrients - mostly nitrogen and phosphorus - from agricultural runoff, wastewater discharge or industrial effluents. When these nutrients build up in bodies of water they cause rapid proliferation of aquatic vegetation such as algae.
Key points to understand about eutrophication:

• Nutrient Overload: The primary cause is an overabundance of nutrients.
• Algal Blooms: Excessive nutrient levels lead to dense algal blooms which can block sunlight from reaching other aquatic plants.
• Oxygen Depletion: When the algae die and decompose, the process consumes oxygen in the water, leading to hypoxic (low oxygen) conditions.
• Impact on Aquatic Life: Low oxygen levels can cause fish kills and reduce biodiversity as many aquatic organisms cannot survive in such conditions.

Applied Knowledge

Imagine a local lake that has become popular for recreational activities like fishing and swimming; unfortunately, local agricultural practices have led to increased runoff containing fertilizers rich in nitrogen and phosphorus entering it - creating massive algal blooms which turn it greenish-brown in appearance and murkiness.
As these algae die off, their decomposition depletes oxygen levels in the water, leading to fish kills and making life hard for aquatic creatures - this affects wildlife as well as local communities who rely on lakes as recreational sites and tourist destinations.
This real-world example illustrates how eutrophication can have widespread ramifications for ecosystems and human activities alike.
