Marine Ecosystems

Warm-Up Write your homework – leave it out to be stamped Update your Table of Contents for today! REVIEW: What is an ecosystem? What are biotic & abiotic factors? What are water ecosystems called? Land ecosystems? How can they be connected? Our focus today is marine ecosystems…what does marine refer to? Date Session # Activity Page 5/19 & 5/20 6 Marine Ecosystems & Organisms Note Guide 8 Marine Vocabulary Swim Blendspace 9

Intertidal zone Neritic zone Oceanic zone

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

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 http://oceanservice.noaa.gov/facts/estuary.html

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

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

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

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

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

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

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

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

Marine Vocabulary Swim Use the Blendspace to go through the rest of the essential Ocean Zones, Ecosystems, Resources and Processes within the ocean. 1A class code = iuyx 3A class code = tyjw 4A class code = obbq 1B class code = mzry 3B class code = uwvk 4B class code = pibl
