  • Aquatic biomes

    1. 1. WATER BIOMES
    2. 2. WATER BIOMES• 75% of the earth surface is water.• Most of the biosphere is, in fact, water ecosystems.
    3. 3. Water zones Depth - water zonesPhotic zone:Uppermost, Photosynthesis.Aphotic zone: no light, no photosynthesis.Benthic zone:Sea bottom, lake bottom, riverbed.
    4. 4. Light penetration Source:http://curriculum.calstatela.edu/courses/ builders/lessons/less/les5/les5gifs/sealight.jpg
    5. 5. CategoriesFreshwater Rivers, streams, creeks, bayous.• Flowing-water biomes.• Standing-water biomes. Lakes, ponds.Both• Wetlands. Marshes, swamps, bogs, mangrove swamps.Saltwater• Marine biomes. Ocean, seas, reef.
    6. 6. Flowing water.
    7. 7. Flowing water Moving water picks up sediment and carries it downstream. Sediment transport: new landforms. Movement renders oxigen-rich water. Mosses, fishes: salmon, trout. Eroding effect: mountains, deep canyons.
    8. 8. Standingwater
    9. 9. Standing water Ponds. Ponds are completely photic, plankton is present. Turtles, fishes, frogs, birds, herbaceous plants, etc. LakesBenthic zone: Catfishes, moss eaters, deep algae.
    10. 10. Inlandwetland.
    11. 11. Inland wetland Bogs, swamps, marshes. Covered all the time by water. Trees, shrubs, herbs, lillies (lirio). Birds, frogs, toads, fish, insects, crocodiles. Everglades.
    12. 12. Coastal wetland.
    13. 13. Coastal wetland Regions along the seacost periodically covered by salt water. Mangrove swamps, Salt marshes.Fishes, crabs, shrimps, mudskippers, amphibians, toads, birds, insects.Woody shrubs, trees, vines, mosses.
    14. 14. La Tobara Coastal wetland San Blas, Nayarit. near puerto vallarta.
    15. 15. Estuary.
    16. 16. EstuaryShallow Areas where fresh water and salt water mix. River sediments are deposited here. Nor fresh nor salty. Nutrient-rich. MANY kinds of fishes,crustaceans, mollusks, predators as birds.
    17. 17. Marinezones.
    18. 18. Marine Zones - Overall 70 % of the earth’s surface. Biotic factors change abruptly through depth. Salinity and temperature vary from place to place. VERY diverse (”Rainforest” of water biomes)Coastal zones: 10% of the marine biome, contain 90% of marine life.
    19. 19. Marine zonesB.-Intertidal.E.-Neritic.F.- Oceanic.G.- Photic zone.D.-Benthic zoneA.-Aphotic zone.C.- Pelagic zone.H.- Abyssal Zone
    20. 20. Intertidal (Beach)Large variations in salinity.Litoral.Large variations in temperature.Uneven flow, tides.Crabs, sponges, starfish, tidepool1.jpgsea cucumber, anemones,coraline algae, snails.
    21. 21. Neritic ZoneLying over the continental “shelf”.Bays.Rich in mineral nutrients from land.Proliferation of Phytoplankton andalgae.Oysters, coral animals, algae,dinoflagellates.
    22. 22. Oceanic (epipelagic) zone “Open ocean”. Poor in mineral nutrients from land. Less organisms than neritic. Sharks, mackerels, tuna, seals, jellyfish, sea lions, sea turtles, sting rays.
    23. 23. Photic zoneEnough light for phytoplankton,plants.Includes epipelagic and neriticzones.Depth: up to -200m.More: Grunts, fishes, squids.
    24. 24. Aphotic zoneNo sunlight for phytoplankton, plants.Complete darkness.No plants or algae.More: octopus, deep-sea fishes,hatchet fish, viper fish, deep-seasquids, nautilus.Bioluminiscent, large eyes, stalking.
    25. 25. Benthic zone Bottom-dwelling organisms. Neritic is also part of the benthic zone. Sea stars, Shrimps, sea crabs, clam oysters, urchins, worms, sponges, anemones. Abyssal zone (deeeeeeeep): Leas organisms.
    26. 26. Aphotic zone Eunice Edwards
