| eutrophication |
Too many nutrients entering an ecosystem (nutrient loading) can cause large algal blooms or other growth spurts followed by natural die-off and decay which results in a decreased amount of oxygen available. This can lead to a dangerous cycle of die-offs, which use oxygen in the decay process leading to more die-offs due to low oxygen levels.

The process by which lakes and ponds become enriched with dissolved nutrients, resulting in increased growth of algae and other microscopic plants.

| eutrophication |
A process in which a water body becomes rich in dissolved nutrients, often leading to algal blooms, low dissolved oxygen, and changes in the composition of plants and animals in the water body. This occurs naturally, but can be exacerbated by human activity which increases nutrient inputs to the water body.

| eutrophication |
The introduction of an excessive amount of nutrients (notably nitrogen and phosphorus) into an aquatic ecosystem causes a proliferation of algae. Decomposing algae consumes a great deal of oxygen, endangering fish and other aquatic animals. Eutrophication occurs most often in ecosystems where water is renewed very slowly, such as deep lakes.

| eutrophication |
the over-enrichment of a water body with nutrients causing increased phytoplankton growth. Secchi disk depth can be a good measure of eutrophication, especially in lakes. Secchi disk depths for eutrophic lakes ranges from 1.5 - 3 meters, while depths for oligotrophic (nutrient-poor) waters are greater than 6 meters. Ultraoligotrophic waters can have Secchi disk depths greater than 12 meters!
