3 The habitat 3 distinct zones on barrier islands Subtidal zone
Intertidal zone Supratidal zone

4 Subtidal Zones Crashing breakers with swirling sand and shallow water
Permanently submerged Extends down the continental shelf Exposed briefly during extreme low tides (around full or new moon events)

5

6 Intertidal zone Alternately covered and exposed by tidal waters
AKA foreshore or seashore Above the water usually unless its high tide Areas include steep rocky cliffs, sandy beaches or wetlands Specialized organisms live here due to salt water interacting with fresh rain water

7

8 Supratidal Zone Dry, sandy zone that extends to the base of the sand dunes AKA splash zone or spray zone Above the tide but regularly splashed with salt water Seawater effects these areas more during storms Organisms living here are exposed to fresh air, fresh water (rain), cold, heat and predation by land animals and seabirds

10 Sketch in your notebook

11 The Community The appearance will change day to day based on abiotic factors (wind, weather, etc) Specialized area for only a small variety of species to survive here More species have adapted to live here

12 The Community

13 Producers Subtidal zone has thousands of microscopic plants called phytoplankton which are the main producers Single celled, free floating Examples include Diatoms, Dinoflagellates, Blue Green Algae Nourished by inorganic nutrients Picture magnified 100X

14 Diatoms Most common phytoplankton
Form colonies in the shapes of ribbons, fans, zigzags or stars Unique because the are single cells enclosed within a cell wall made of silica (frustule) Frustules show wide diversity of patterns Found in fossil and originate in the Jurassic period

15 Dinoflagellates Meaning “whirling whip”
Found mostly in marine plankton but also in fresh water Populations are distributed based on temperature, salinity and depth All are producers however some are known to be mixotrophic-meaning they also ingest prey (protozoa)

16 Blue Green Algae Bacteria that can perform photosynthesis
Produce oxygen and said to have helped converted the early atmosphere to an oxidizing one Very genetically diverse Occupy a broad range of habitats across all latitudes, freshwater, marine, and terrestrial ecosystems Found in extreme niches, such as hot springs and hypersaline bays

17 Sargassum Seaweed Free float algae
Has berry like bladders that keep it afloat Large rooted seaweed cannot survive on the crashing surf Large masses are seen on the shore after a storm

18 Ocean Beach Consumers

19 Primary Consumer-Zooplankton
Zoo=animal; plankton=wanderer Examples are: Isopod, copepod, and amphipod

20 Secondary consumers Go through a life cycle to reach adulthood
Larval stage is seen amongst the phytoplankton Invertebrates Barnacles Mollusk Worms Horseshoe crab Starfish Crab Sea Cucumbers

21 White Boards-Primary Consumer
Divide into 6 groups (3 each) Group 1 & 4-Isopods Group 2 & 5-Copepod Group 3 &6-Amphipod Use text book, laptops or cell phone to research: What is their prey? What is their predators? What is their life cycle? Draw a picture At least 3 facts on your primary consumer

22 Primary Consumer-Zooplankton
Zoo=animal; plankton=wanderer Examples are: Isopod, copepod, and amphipod

23 Symbiotic Relationships

24

25 Symbiotic Relationships
Mutualism-Both benefit Commensalism-One benefits; Other not helped or harmed Parasitism-One benefits; Other is harmed

26 Layers of the Ocean

27

28 Layers of the Ocean Intertidal zone-Littoral Zone (between tides)
Subtidal zone divides into 3: Neritic Zone-low-tide to the edge of the continental shelf Bathyal Zone-slope down to 2000 meters Abyssal Zone-Deep ocean floor

29 Neritic Zone Photosynthesis will take place Most sea life is here

30 Bathyal Zone Located above the abyssal zone Known as midnight zone
NO photosynthesis takes place Difficult for fish to live Must have adaptations

31 Abyssal Zone Known as the Pelagic zone Always dark and cold
Lack nutrients; NO photosynthesis Fish must be adapted for great pressure to survive here
