Question: 408

18.

Organisms that live in the abyssal zone would need all of the following adaptations EXCEPT

A. ability to withstand extreme pressures
B. well-developed eyes
C. tolerance of cold temperatures
D. ability to survive in areas of low nutrient density
E. ability to utilize limited resources

Correct Answer: B

Explanation:

B The abyssal zone is characterized by extremely high water pressure, extreme cold, darkness, and very low nutrient density. Organisms that live here must be able to tolerate all of those conditions. Well-developed eyes would not be useful, because there is no light in this deepest part of the ocean. Remember, this is a LEAST/EXCEPT/NOT question. Circle the word "EXCEPT" and draw a vertical line to remind yourself to choose the "wrong" answer.
