How are seagrasses, cordgrasses, and mangroves adapted to living in marine environments ?

Like seagrasses, mangroves flourish as a result of the protection from violent ocean waves offered by coral reefs. Mangroves benefit both seagrasses and coral reefs primarily by mitigating shoreline erosion and thereby preventing harmful amounts of sediment from entering coastal waters.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
