Estuaries/Intertidal Zones
What is the term used to describe an organism that has lost water or dried out?
What is desiccation?
What is the top layer/zone called ?
What is the photic/epipelagic zone?
Corals are a type of this invertebrate.
What are cnidarians?
List one abiotic factor that changes with ocean depths.
What is increased density (nutrients/salinity), decreased temperatures, increased pressure, decreased sunlight, etc.)?
This type of pollution can affect organisms in the deep sea and also contributes to the Great Pacific Garbage Patch.
What is/are plastic/microplastics?
What type of water do estuaries typically have?
What are the small primary producers at the base of the epipelagic food web?
What are phytoplankton?
Why is coral part stone?
What is it's calcium carbonate skeleton?
Particles from dead organisms, zooplankton, and other floating material that make up the base of the deep ocean food web.
What is Marine Snow?
The "Deepwater Horizon" case is an example of which type of marine pollution?
What is an oil spill?
What are 3 types of estuaries?
What are Coastal plains, Fjords, Bar-Built, Tectonic?
How does salinity change with depth in the ocean?
Salinity increases with depth because saltier water is more dense and sinks.
What makes corals colorful?
What is the symbiotic relationship between corals and photosynthetic zooxanthellae?
This can provide food for many deep sea organisms for over 100 years.
What is a Whale Fall?
Excess nutrients from lawns and agriculture runoff into the ocean and can cause harmful algae blooms such as red tide. What are 2 effects of red tide?
What are 2 adaptations of organisms that live in the intertidal zone?
"Clamming up", burrowing, etc.
Includes the deepest parts of the ocean.
What is the hadalpelagic zone?
What happens during coral bleaching?
What is the corals become stressed and expel the zooxanthellae, leaving a weak skeleton behind?
This type of deep sea environment spews minerals and gases from within the Earth. Organisms such as tube worms and chemosynthetic bacteria feed on the releases.
What is a hydrothermal vent?
How do greenhouse gases (example: carbon dioxide) in the atmosphere affect the ocean?
Increased acidity, increased temperatures, coral bleaching, less oxygen availability, etc.?
What are 2 reasons why estuary reserves are important?
They provide nurseries for young estuarine organisms, recreational opportunities, support seafood industry, support economies, water filtration, storm buffers, etc.
Name the 5 layers of the ocean.
What is Epipelagic Zone,Mesopelagic Zone,Bathypelagic Zone,Abyssopelagic Zone,Hadalpelagic Zone
What is the nickname given to coral reefs due to their high biodiversity?
What is "Rainforests of the Sea"?
What is it called when organisms float up to the upper ocean zones at night and revert back into the deeper zone in the morning?
Diel migration
List 2 examples of renewable and nonrenewable marine resources.
Renewable: biological, algin, marine energy
Nonrenewable: physical resources (minerals, freshwater, methane hydrants, etc.)
