1. Freshwater Marine Estuary

Estuary

2. Freshwater
NO SALT IN THE WATER!!
Less than 1% salt in the water

3. Examples Wetlands—land that is saturated with water
examples: Marshes & Swamps
Rivers
Streams
Lakes
Ponds

4. Climate
Can be found in mostly any climate

5. Ponds and Lakes Littoral Zone Open Water Zone
(closest to the edge, shallow, sunlight reaches, lots of plants)
Open Water Zone
(extends from littoral zone, only as deep as light can reach)
Deep Water Zone
(below open water zone, no light reaches)

6. Abiotic Factors -Speed of the water -Depth of the water
-How much light reaches the water
-Range in size

7. Wetlands (Marshes & Swamps)
-Areas of standing water that support aquatic life
-Highest species diversity
-May be dry part of year
-Marshes: treeless, shallow area along the shores of freshwater ecosystems, where reeds and grasses grow
-Swamps: low-lying area where trees and shrubs grow such as willows and vines

8. Animals Fish Ducks Invertebrates—crayfish, shrimp, insects, etc.
Amphibians
Reptiles
Muskrats
Turtles
Frogs
Birds

9. Plants
Cattails
Water lilies
Moss

10. Marine
Oceans
Coral Reefs
Estuaries
Salt Water!

11. -Great species diversity -”Zones” determined by depth
Characteristics
-Largest Ecosystem
-Great species diversity
-”Zones” determined by depth

12. Location
Oceans—Pacific, Atlantic, Indian, Arctic, Southern

13. Climate Gets colder and darker the deeper it gets.
Some places never get sunlight.

14. Intertidal Zone (ocean meets land, waves are crashing, sunlight)
Neritic Zone (deeper, ocean floor starts to slope, warm, sunlight)
Oceanic Zone (sea floor drops sharply, deep water, plankton)
Benthic Zone (ocean floor, cold, no sunlight, unusual creatures)
Oceans

15. Coral Reefs -Found in warm, shallow water -Barriers along continents
-Dominant organism is coral

16. Estuaries -Where ocean water meets fresh water
-Mixture of fresh & salt water
-Salt content is always changing
-Nutrient Rich
-Brackish water
-Unique ecosystem

17. Animals Sharks Fish Whales Invertebrates—echinoderms, mollusks, etc.
Some snakes

18. Plants
Plankton, algae, kelp & seaweed (protists)
