Explanation:

Eutrophication is the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen, phosphorus, or both.
Eutrophication can be a natural process in lakes, occurring as they age through geological time. Human activities can accelerate the rate at which nutrients enter ecosystems.
Runoff from agriculture and development, pollution from septic systems and sewers, and other human-related activities increase the flux of both inorganic nutrients and organic substances into terrestrial, aquatic, and coastal marine ecosystems (including coral reefs).
