What’s an Estuary?.

Wetland Environments By, Janet Hooks : ). ECOSYSTEM- All of the BIOTIC (living) things and all of the ABIOTIC (non-living) factors in an environment.

Wetlands  Wetlands contain fresh water for part of the year -trap and filter sediments and pollutants -protect shorelines from erosion -spawning grounds.

What do these abiotic factors have in common? What is different about them?
