Warm-Up Update your Table of Contents Write your homework – leave it out to be stamped Get vocab cards out to be checked Put your Titanic Article in the basket Read the “Marine Ecosystems” article and answer the questions on page 42 of your notebook DateSession # ActivityPage # 11/1528Marine Ecosystem Warm-up and Ocean Resource List42 Ocean Zones & Marine Ecosystems Note Guide43

Marine Ecosystems Q & A: 1. What are biotic and abiotic factors? 2. What is an ecosystem? 3. Aquatic ecosystems can be classified into 2 categories: What are they? 4. List as many types of marine ecosystems as you find in the article. 5. Give 3 explanations as to why aquatic ecosystems are so important for the entire planet.

Ocean Resource List Start a list of resources we receive from our oceans and add to it throughout the lesson:

Intertidal Zone Shoreline area that falls between the high tide and low tide mark.

Life in the Intertidal Zone Animals in this area are able to adapt to being both underwater and in open air Common life forms include: Crabs Urchins Starfish Clams Snails Mussels

Neritic Zone The ocean zone that slopes down from the shoreline towards the ocean floor.

Life in the Neritic Zone Animals in the Neritic Zone have access to both shallow and deeper water. The life in this zone is very diverse! Common life forms in the Neritic Zone: Sea Turtles Dolphins Seals

Oceanic Zone The oceanic zone is made up of the open waters of the ocean

Life in the Oceanic Zone Marine life varies greatly due to the changes in depth… What are the challenges to life as the water gets deeper? Common Life Forms: Whales Sharks Squid Angler Fish (deep)

Intertidal zone Neritic zone Oceanic zone

Marine Ecosystems: Within these zones are many different and separate ecosystems.

Coral Reefs Extremely diverse ecosystems that need very specific conditions to survive. “The Rainforest of the Ocean”

Estuary An area where fresh water from a river mixes into the salt water of the ocean

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

Kelp Forests Large underwater forests of brown algae that provide a habitat for animals and many resources for humans

Salt Marshes A transitional area between land and water that acts like a filter for pollution

Mangrove Forests A transitional area between land and water in tropical areas that transfer energy from land to sea through the food chain

Tide Pool Small habitats on shore that are underwater at high tide and exposed to air at low tide

Back to Ocean Resources… Have you added anything to your list?

Ocean Assessment: Create a collage of Marine Resources You must include at least 10 pictures Number each picture and provide a corresponding explanation as to how it represents a marine resource on the back
