Eutrophication is the excessive growth of algae and other plants due to an increase in nutrients (such as nitrogen and phosphorus) in a body of water, leading to harmful effects on aquatic ecosystems.
Think about adding too much fertilizer to your garden. The plants may grow rapidly at first, but eventually, they become overcrowded and start competing for resources. Similarly, eutrophication causes an overgrowth of plants that disrupts the balance within aquatic ecosystems.
Algal Bloom: An algal bloom occurs when there is a rapid increase in the population density of algae due to eutrophication.
Nutrient Runoff: Nutrient runoff refers to excess nutrients from fertilizers or animal waste entering bodies of water through surface runoff or groundwater flow, contributing to eutrophication.
Trophic Cascade: A trophic cascade happens when changes at one trophic level (e.g., excessive algae growth) affect multiple other trophic levels in an ecosystem.
