Key Terms:
  • estuary
  • salt marsh
  • mangrove swamp
  • barrier island
  • coral reef
Main Ideas:
  • Marine ecosystems are identified by the presence of salt water and include coastal wetlands, coral reefs, oceans, and polar ecosystems.
  • Estuaries are among the most productive of ecosystems because they constantly receive fresh nutrients from a river and from an ocean.  Estuaries provide habitats for a multitude of plants and animals.
  • Coral reefs are susceptible to destruction because they must remain at tropical temperatures and they must receive a large amount of sunlight.  Coral reefs provide habitats for approximately one-fourth of all marine species.
  • Almost every person has an impact on aquatic ecosystems.  Through understanding how we affect aquatic ecosystems, we can reduce the negative effects we have on them.
