Presentation Transcript

  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
