Pelagic Zone

​Question #13 57% correct

​There are 5 major pelagic zones in the ocean. You will need to know these zones for the Unit Test.

​​

NOTE: chances are if you missed this question, you missed #12 which was an application of the information here.​

Multiple Choice

Question #12: If a fish lives deep within the Mariana Trench, what pelagic environment is that fish living in?

• Abyssopelagic

• Epipelagic

• Hadopelagic

• Mesopelagic

Multiple Choice

Phytoplankton need sunlight for photosynthesis. In what pelagic zone are phytoplankton likely to thrive?

• Epipelagic

• Mesopelagic

• Bathypelagic

• Abyssopelagic

Multiple Choice

Anglerfish use bioluminescence to attract prey because there is not sunlight in the zone in which they live. Based on the diagram shown, where are we likely to find the anglerfish?

• Mesopelagic

• Bathypelagic

• Abyssopelagic

• Hadopelagic

​Question #16

​In the image above, which organisms are benthic?  Select all that apply.

​Question #22

​Using the image above and your knowledge of energy transfer between trophic levels.  How much energy would be transferred by 40,000,000 kcal of phytoplankton to the Baleen Whale?

​

What you need to remember is only 10% of the energy is transferred from one trophic level to the next. ​

​

Let's practice the math.​

Multiple Choice

Following the energy flow in the Antarctic food web from phytoplankton to copepods to small fishes to the leopard seal, how much energy is transferred by 200,000,000 kcal of phytoplankton to the leopard seal?

• 78,900

• 7,890

• 789

• 78.9 kcal
