1. Aquatic Biomes Freshwater – Lakes and Ponds – Streams and Rivers – Marshes and Swamps Marine – Oceans – Coastal wetlands

2. Freshwater Lakes and Ponds Very small and seasonal to very large and deep Summer top layer warmest Winter bottom layer is warmest

3. Lake and Pond Life Insects Frogs, Turtles Fish – feeders and predators Plants- more along shore less the deeper you go. – Ponds will have plants even in the deepest parts Microscopic life

4. Rivers and Streams Bodies of water moving in one direction Source – spring, snow melt, lake Cold and fast moving near source – Higher oxygen levels Middle – diverse ecosystem, slower moving Mouth – warmest, lowest oxygen levels

5. River Life Fast moving cold water – Trout and Dobson fly Middle parts of river – Bass, turtles, frogs – Otters Mouth of the river – Carp and catfish

6. Wetlands Swamp Trees Poorly drained land near rivers Marsh Low flat land Shallow waters Reeds and cattails Rich sediments

7. Wetland Animal Life Ducks, geese Muskrats, nutria Turtles, frogs, newts, salamanders Alligators

8. Wetland Plant Life Marshes – Cattails Swamps – Bald cypress

9. Biotope Aquarium – Amazon River

10. Biotope Aquarium – African Great Lakes

11. Marine Biome Oceans Largest biome on the planet Divided into zones according to how much light penetrates the water: – Sunlight – Twilight – Midnight

12. Sunlight Zone Down to about 600 feet below surface 90 % of marine life lives here Photosynthesis can take place here Includes tidal zones

13. Twilight Zone From 600 to 3000 feet below the surface Very little light No plant life Specialized animals

14. Midnight Zone 3000 feet to the bottom No light – no plants Cold – except by thermal vents Very high pressure

15. Coastal Wetlands Halophytic plants – salt loving plants Where fresh water meets salt water Brackish water Erosion and flood control

16. Salt Marshes Where rivers meet oceans Temperate Abundant bird life Tidal flooding – floods everyday Sand or mud flats

17. Mangrove Swamps Mangrove trees – tangled roots Pneumatophores – special adaptation that supplies tree with air Tropical Protects shoreline
