eutrophic
Definition
- Adjective:
- (Ecology) Describing a body of water, such as a lake or pond, that is rich in dissolved nutrients (like nitrogen and phosphorus), which often leads to excessive plant and algal growth. This process, called eutrophication, can deplete oxygen levels and harm aquatic life.
Usage
The term eutrophic is a scientific adjective used primarily in environmental science, ecology, and limnology (the study of inland waters). It describes the nutrient-rich state of a water body, which is often a result of natural aging or human-induced pollution (e.g., from agricultural runoff or sewage). It is typically used in contrast with oligotrophic (nutrient-poor) and mesotrophic (moderately nutrient-rich).
Examples
- The once-clear mountain lake has become eutrophic due to fertilizer runoff from nearby farms.
- Scientists monitor the reservoir to prevent it from becoming eutrophic.
- A eutrophic pond is often characterized by murky water and dense surface algae.
Advanced Usage
- Eutrophication (n.): The process by which a body of water becomes progressively enriched with nutrients, leading to the conditions described by the adjective .
- The rapid eutrophication of the coastal bay was caused by wastewater discharge.
Variants and Related Words
- Eutrophication (n.): The process of becoming eutrophic.
- Eutrophy (n.): The state or condition of being eutrophic (less common).
- Oligotrophic (adj.): (Of a body of water) deficient in plant nutrients and containing abundant oxygen in the deeper parts.
- Mesotrophic (adj.): (Of a body of water) having a moderate amount of dissolved nutrients.
Synonyms
- Nutrient-rich (in the specific context of water bodies)
- Fertile (in the specific ecological context)
Antonyms
- Oligotrophic
- Nutrient-poor
Adjective
-
(ecology) of a lake or other body of water rich in nutrients and subject to eutrophication
