Read each question carefully and answer to the best of your ability. Refer to the diagram of ocean layers as needed.

Observe the diagram of the ocean layers below:

Ocean Zones Cross Section

1. Which ocean layer is characterized by the presence of sunlight and supports the vast majority of marine life through photosynthesis?

a

Abyssal Zone

b

Hadopelagic Zone

c

Epipelagic Zone

d

Bathypelagic Zone

2. The thermocline is a distinct layer in the ocean where there is a rapid change in which of the following properties?

a

Salinity

b

Pressure

c

Temperature

d

Oxygen content

3. The deepest parts of the ocean, often found in trenches, are referred to as the   Zone.

4. Organisms in the aphotic zone often rely on   for energy, a process that uses chemical reactions instead of sunlight.

5. Describe two environmental challenges faced by marine organisms living in the Bathypelagic Zone and explain how they might adapt to these conditions.

6. Bioluminescence is a common adaptation among organisms in the Epipelagic Zone to attract prey.

T

True

F

False

7. The Photic Zone is another name for the Epipelagic Zone, where sunlight penetrates sufficiently for photosynthesis.

T

True

F

False

Match each ocean layer with its primary characteristic.

8. Epipelagic Zone

 

a. Complete darkness, high pressure, cold temperatures

9. Mesopelagic Zone

 

b. Sunlight penetration, photosynthesis occurs

10. Bathypelagic Zone

 

c. 'Twilight zone', some light but not enough for photosynthesis
