Passage V

Some oceanic shrimp are vertical migrators. For vertically migrating species, most of the population is found at the bottom of their depth range during the day and at the top of their depth range at night. Table 1 shows the depth ranges and water, protein, lipid, and carbohydrate content of 3 vertically migrating (vm) species of shrimp and 3 nonmigrating (nm) species of deep-sea shrimp. Figure 1 shows water temperature and oxygen partial pressure at various ocean depths.

25. Assume that shrimp of a newly discovered species of vertically migrating shrimp were captured at night at a minimum depth of 200 m. Assume that only temperature limits the range of this species. Based on the information in Figure 1, one would predict that the maximum water temperature these shrimp could survive in would be:

Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

It can be seen from figure 1 that the temperature at a depth of 200 m is about 7.5°C;

Because it can be seen from figure 1 that the temperature decreases with the increase of water depth, so the minimum depth of 200m means the highest temperature is 7.5°C
