OCEAN ZONES Chapter 13 Section 2 Ocean Zones Chapter 13 Section 3
Benthic Environmenton the bottom from shore to deep ocean Intertidal Zonewhere the ocean meets the land Sublittoral Zonecovers the continental shelf Bathyl Zonezone that covers the continental slope Abyssal Zonelargest zone, 2000 -6000 meters deep Hadal Zone 6000 meters to the deepest ocean trench
Intertidal zone Shoreline, in the tide Animals adapted to water and dry land Receives the most sunlight Clams, mussels, starfish, crabs, shrimp, anemones, sponges
Sublittoral Zone Covers the continental shelf Sunlight, pressure and temperature constant Coral
Bathyl Zone Edge of continental shelf, along slope, to abyssal plain 200 to 4000 meters Little sunlight Sponges, octopus, sea stars
Abyssal Zone No plants and very few animals Largest ecological zone Can reach 4000 meters Crabs, sponges, worms and sea cucumbers, anglerfish Many animals live around hot water vents called black smokers
Black Smokers
Hadal Zone Deepest zone 6000 -7000 meters deep Sponge, clam and worms Fewest amount of animals
The Pelagic Environment- water in the ocean Neritic zone-water that covers the continental shelf Oceanic zone-rest of water in the ocean
Neritic Zone Warm, shallow Much sunlight Most marine organisms, plants and animals Fish, plankton, mammals Whales, dolphins
Oceanic Zone Covers the ocean floor beyond the continental shelf Deep regions very cold, no sunlight Fewer organisms Pressure greater
3 Groups of Marine Life Plankton Nekton Benthos
Plankton are tiny openwater plants, animals or bacteria. These organisms range in size from microscopic bacteria and plants to larger animals, such as jellyfish. Plankton generally have limited or no swimming ability and are transported through the water by currents and tides. Plankton communities serve as a base for the food chain.
Nekton Animals that swim or move freely in the ocean are nekton. Nekton come in all shapes and sizes. They live in shallow and deep ocean waters. Most nekton eat zooplankton, other nektons or they scavenge for waste
Benthos The benthos live on the ocean floor. Starfish, oysters, clams, sea cucumbers, brittlestars and anemone are all benthos. Most benthos feed on food as it floats by or scavenge for food on the ocean floor.
