Passage II

An experiment was conducted to determine how seawater temperature and salinity affect food consumption and growth in Scophthalmus maximus (a species of fish). The table shows, for each of 8 trials, average total food consumption, CT, and average gain in body mass for S. maximus kept at various temperature and salinity combinations. Each trial involved the same number of fish and lasted the same number of months.

Table adapted from Albert K. Imsland et al., "The Interaction of Temperature and Salinity on Growth and Food Conversion in Juvenile Turbot (Scophthalmus maximus)."@2001 by Elsevier Science B. V.

8. Consider Trials 1-4. Based on the table, as salinity increased, did average CT increase or decrease, and did average gain in body mass increase or decrease?

Answer and Explanation

Your Answer is

Correct Answer is H

Explanation

In the chart, the average Ct of Trial 1-4 is decreasing, and the corresponding body mass is also decreasing.
