Oceanic zone

4. Marine Ecosystems:
Within these zones are many different ecosystems, but some are transitional areas between 2 different ecosystems making them more specialized.

5. Estuary
An area where fresh water from a river mixes into the salt water of the ocean creating “brackish” waters
Nursery for many aquatic & terrestrial organisms

6. Estuary Demo
Salt Water is denser than freshwater therefore it does not fully mix…watch what happens in our mini estuary

7. Salt Marsh A common habitat within estuaries
Acts as a filter for pollution
Protects the shoreline from erosion

8. Mangrove Forest Stabilize the coastline from erosion
Intricate root system provides protection for organisms

9. Essential Marine Organisms
Within these ecosystems there are different categories of organisms, all of which play a role to keep the ecosystem functioning…

10. Algae Most important photosynthesizing organisms on Earth
Algae are the foundation of aquatic food webs and have many economic benefits

11. Plankton
A diverse group of organisms that float with the ocean current because they are too weak to swim

12. Nekton
Nekton = “free-swimmers,” organisms that are strong enough to swim freely and independently of the ocean currents.

13. Benthos Benthos = “bottom feeders”
Called benthos because they live in the benthic zone/ocean floor
