What is the continental slope?
The amount of salt dissolved in the ocean
What is salinity?
Phytoplankton (a plant) is an example of this part of a food chain.
What is: a producer?
This describes the first 200 meters of the ocean
What is: the sunlight zone?
These describe the clockwise and counter clockwise movement of ocean currents.
What are gyres?
These determine the salinity of ocean water that is near land.
What are rivers or runoff?
The connections between food chains form this
What is: a food web?
This describes ocean depths of 1,000 meters or more
What is: the midnight zone?
This is the wide flat area that extends out from the continental rise and represents the true ocean floor.
What is the abyssal plain?
This is what happens to the amount of sunlight as you go deeper into the ocean.
What is: decreases?

What are: consumers?
This ocean feature is the deepest measured point on earth
What is: the Mariana Trench?
These two things cause deep water/deep ocean currents.
What are: changes in temperature and salinity?
This feature begins at the border of a continent where the land slopes gradually away from the shore.
What is the continental shelf?
This is the direction of energy flow in a food chain.
What is: from the prey (animal or plant being eaten) to the predator (animal doing the eating)?
What is: bioluminescence?
