What is 80%.
100
What dominant factor controls phytoplankton growth?
What is sunlight (and nutrients).
100
What is the difference between autogenic and allogenic ecosystem engineers? Give examples of each type.
Autogenic- create habitat Allogenic- convert materials in the environment from one state to another.

What is the horseshoe crab.
200
Name a specific nutrient that is contributing to harmful algal blooms and resulting hypoxic conditions in coastal regions.
What is nitrogen (and phosphorous).
200
What is the term for the condition of water with low oxygen?
What is hypoxia ('anoxia' means no oxygen).
300
What is the zone of the ocean called that at the water's surface? Name three types of organisms we saw on our trips that live in this ocean zone.
What is the pelagic zone. Examples include phytoplankton, species of fish, etc.
300
Remembering the global map of phytoplankton distribution, where are most phytoplankton concentrated?
What is along the coasts! specifically western coasts of South America, Africa and polar waters.
300
What region of Long Island sound has the highest occurrence of dead zones and hypoxia- the southern end (towards New York city) or Northern end (towards Boston)?
What is the southern end, where the sound is narrower and the waters are further from the mouth, unable to flush out as easily. Also there is increased pollution and runoff towards New York city.
300
How are macro-algae (more commonly known as seaweeds) classified?
What is by the color of their pigment- green, red and brown algae.

What land mass could we see across the water on the second field trip?
What is Long Island.
400
Do anadromous fish spawn in freshwater or saltwater?
What is spawning in freshwater; living in saltwater.
400
Why are plankton very abundant in polar waters?
What is because of upwelling of nutrient rich bottom waters.
400
How do tidal forces affect the earth? Act out the difference between spring and neap tides.
Bulge water and the crust, cause 4 tides a day.
400
Name an example of a physical factor that affects marine organisms living in the tidal zones (think back to observations on our second field trip).
What is extreme temperature fluctuations, desiccation (drying when the tide goes out), competition between species, etc.
400
What forces carved out Long Island Sound 15,000 years ago?
What are glaciers.
