MARINE ECOSYSTEMS: MARINE ECOSYSTEMS
Slide 2: Factors that divide the ocean into distinct marine life zones : the availability of sunlight the distance from shore water depth.
Different Zones of Marine Ecosystem: Different Zones of Marine Ecosystem
Intertidal Zone: Intertidal Zone The area where land and sea meet and overlap (the zone between high and low tides)
Slide 6: The upper part of the ocean into which sunlight penetrates. Photic Zone
Slide 7: Benthic Zone Lowest level of a Ocean, including the sediment surface and some sub-surface layers.
Estuary: Estuary A semi-enclosed costal body of water where fresh river water mixes with salty sea water.
Slide 9: Estuary
Kelp Forests: Kelp Forests Kelp forests are underwater areas with a high density of Kelp. They are recognized as one of the most productive and dynamic ecosystems on Earth
Marine Organisms: Marine Organisms
Food Chain: Food Chain Phytoplankton Unicellular algae Zooplankton Planktonic animals that feed on phytoplankton Nekton Animals that feed on Zooplankton
Phytoplankton (Plant Plankton): Phytoplankton (Plant Plankton) The most important community of primary producers in the ocean. They are the foundation of oceanic food chain
Zooplankton (Animal Plankton) : Zooplankton (Animal Plankton) Krill Jelly fish Passively drifting or weak swimming organisms that cannot move independently of ocean currents.
Nekton: Nekton Organisms that can move independently of ocean currents by swimming or other means of propulsion.
Coral Reefs: Coral Reefs
Star Fish: Star Fish Animals that live on or near coral reefs
Slide 20: Animals that live on or near coral reefs
Benthos : Benthos The forms of marine life that live on the ocean floor.
