Eutrophication
Follow nutrients through a chain of ecosystem effects.
Lakes, estuaries and coastal waters
What to understand
- 1Excess nutrients can stimulate algal growth.
- 2Decomposition of excess organic matter consumes oxygen, potentially harming fish and other organisms.
The distinction to remember
Nutrient enrichment can lead to oxygen depletion; abundant algal growth does not guarantee healthy water.
Conservation connection
Nutrient-rich runoff and wastewater can worsen enrichment.
