Fish populations in some areas of the ocean have been exhausted by overfishing. This has caused ecosystems to become imbalanced and species to become endangered. The diagram below breaks the ocean's total fish population into three categories—species declining in population (overfished), species growing in population (moderately fished), and species with stable population (fully fished). The graph shows the percentage of the total fish population represented by each category for various years between 1974 to 2000. For example, in 1974, 51% of the population was fully fished, 39% was moderately fished, and 10% was overfished. What can be said about the trend in fish populations between 1974 and 2000? A. The percentage of the total fish population that is fully fished decreased by 18%. B. The percentage of the total fish population that is overfished increased by 18%. C. The percentage of the total fish population that is moderately fished increased by 18%. D. The percentage of the total fish population that is overfished decreased by 18%. Reset Submit
