In land wetlands
Lands located away from coastal areas that are covered with fresh water all part of the time.
Delta
An area at the mouth of a river built up by deposited sediment and often containing estuaries and coastal wetlands.
Cultural eutrophication
Puts excessive nutrients into lakes.
Eutrophic lake
Lake with a large supply of nutrients.
Oligotrophic lake

Estuary
Where a river meets sea.
Coastal zone
Is the warm nutrient- rich shallow water that extends from the high -tide mark on the land to the gently sloping, shallow edge of the continental shelf.

Lakes, rivers, streams, and in land wetlands.
Marine life zones
Oceans and their bays estuaries coastal wetlands shorelines coral reefs and man grove forests.
