Marine Ecosystems Quiz

If an animal is considered benthic, it is typically found:

• In the water column

• At or near the bottom of the ocean

• On the beach

• Breaching or jumping out of the water

If an animal is considered pelagic, it is found:

• Near the bottom of the ocean

• In the water column

• On the beach

• Within ocean sediment

The aphotic zone is a part of the water column where photosynthesis cannot occur

because of the absence of:

• Carbon dioxide

• Oxygen

• Nutrients

• Sunlight

Which of the following is likely to be found at a subduction

zone:

• A barrier island

• An ocean gyre

• A trench

• Elusive species of beaked whales

The deepest zone of the ocean, below 6,000 meters, is called:

• Epipelagic

• Mesopelagic

• Abyssopelagic

• Hadalpelagic

Animals like the great white shark and whale shark can be found in the epipelagic

zone among other areas of the ocean. This means that they can be found:

• Near the surface

• At depth between 1,000-4,000 meters

• In ocean trenches (4,000-6,000 meters)

• Below 6,000 meters

This term refers to a physical location with distinct abiotic conditions

that supports a community of interacting species.

The euphotic zone is:

• In the deep sea below 1,000 meters

• In the well-lit surface layer where plants undergo photosynthesis

• In the uppermost sediment layer of the ocean bottom

• In the deepest sediment layer of the ocean bottom

What term refers to the area of the shore between mean high water

and mean low water?

Consider the following ecosystem: A freshwater lake with a small crustacean species

called Daphnia that feed on phytoplankton. Nutrients from a nearby farm

occasionally run into the lake. The phytoplankton use the nutrients and sunlight to

reproduce. Daphnia’s only predator is a species of mosquito fish that lives in the

lake.

Name three abiotic factors and three biotic factors that comprise this ecosystem.
