Wet lands

Standing water ecosystem Lakes, ponds, puddles H2O circulates within themself Has O2 and nutrients

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
