Eutrophication Explained | Causes, Steps & Effects on Aquatic Ecosystems

Learn what eutrophication is, how it happens, and why it can devastate lakes, ponds, rivers, and coastal waters. In this lesson, Ms. Parrott explains the process of eutrophication, where excess nutrients from fertilizers and animal waste cause massive algae growth and oxygen depletion in aquatic ecosystems. You’ll follow the step-by-step chain reaction from nutrient runoff to algal blooms, decomposer overgrowth, and fish kills — plus how to prevent it. What you’ll learn: Definition of eutrophication How fertilizers and animal waste cause nutrient runoff (leaching) Why nitrogen, phosphorus, and potassium trigger excessive algae growth What an algal bloom is and how it blocks sunlight for aquatic plants How decomposers use up oxygen during decomposition The link between oxygen depletion and fish/animal deaths Prevention strategies for farmers and land managers 📚 Perfect for: AP Biology and AP Environmental Science students Ecology learners studying human impacts on ecosystems Teachers explaining water pollution and conservation 💬 Your Turn: What do you think is the best way to prevent eutrophication in your area?
