Aquatic biomes Aquatic biomes Presentation Transcript

  • WATER BIOMES
  • WATER BIOMES• 75% of the earth surface is water.• Most of the biosphere is, in fact, water ecosystems.
  • Water zones Depth - water zonesPhotic zone:Uppermost, Photosynthesis.Aphotic zone: no light, no photosynthesis.Benthic zone:Sea bottom, lake bottom, riverbed.
  • Light penetration Source:http://curriculum.calstatela.edu/courses/ builders/lessons/less/les5/les5gifs/sealight.jpg
  • 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.
  • Flowing water.
  • 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.
  • Standingwater
  • Standing water Ponds. Ponds are completely photic, plankton is present. Turtles, fishes, frogs, birds, herbaceous plants, etc. LakesBenthic zone: Catfishes, moss eaters, deep algae.
  • Inlandwetland.
  • Inland wetland Bogs, swamps, marshes. Covered all the time by water. Trees, shrubs, herbs, lillies (lirio). Birds, frogs, toads, fish, insects, crocodiles. Everglades.
  • Coastal wetland.
  • 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.
  • La Tobara Coastal wetland San Blas, Nayarit. near puerto vallarta.
  • Estuary.
  • 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.
  • Marinezones.
  • 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.
  • Marine zonesB.-Intertidal.E.-Neritic.F.- Oceanic.G.- Photic zone.D.-Benthic zoneA.-Aphotic zone.C.- Pelagic zone.H.- Abyssal Zone
  • Intertidal (Beach)Large variations in salinity.Litoral.Large variations in temperature.Uneven flow, tides.Crabs, sponges, starfish, tidepool1.jpgsea cucumber, anemones,coraline algae, snails.
  • Neritic ZoneLying over the continental “shelf”.Bays.Rich in mineral nutrients from land.Proliferation of Phytoplankton andalgae.Oysters, coral animals, algae,dinoflagellates.
  • 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.
  • Photic zoneEnough light for phytoplankton,plants.Includes epipelagic and neriticzones.Depth: up to -200m.More: Grunts, fishes, squids.
  • 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.
  • 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.
  • Aphotic zone Eunice Edwards
