Fresh H2O wetlands
Wetlands are ecosystems in which H2O either
covers the soil, may be flowing, or standing over
soil
Fresh, salty, brackish
Three types:
Bogs, marshes, swamps
Estuaries
• Wet lands found where rivers meet the sea.
Contain both fresh and salt H2O. They support
a large number of animals
Salt marshes
Temperate zone estuaries dominated by salt
tolerant grasses at low tide
Stretch from eastern north America from main to
Georgia.
Largest is in Maryland the Chesapeake Bay Maine.
Salt marshes
Mangrove swamps
Costal wet lands in tropical regions in Florida ,
Hawaii
Have salt tolerant trees called mangroves.
Largest in America is the Everglades in Florida
They provide protection to many animals.
Mangrove swamps
Classification of marine ecosystem
Are divided by distance from the shore
Intertidal- extreme change in H2O exposed to air
and temperature
Coastal- shallow photosynthetic sea life ( kelp
forest) coral reefs are in this region
Open- ocean- occurs 90% surface area of world’s
oceans, low levels of nutrients
Benthic zone- is in open ocean floor
Intertidal Zone
Costal zone
