Question

Fish populations and other aquatic resources are likely to be affected by changes in what aquatic factors? a. water temperatures b. disease c. water quality d. all of the above Fish populations and other aquatic resources are likely to be affected by changes in what aquatic factors: water temperatures

Answer 1

The correct answer is - d. all of the above.

The fish populations and other aquatic resources can be affected by multiple factors. The water temperature is a defining factor, if it is colder than lots of marine life will dye out and be replaced with other species, and vice versa, if its too warm lots of marine life adapted to colder conditions will die out. Diseases are always an impact factor in any environment, so if a dangerous, fatal, disease appears, it can demolish the populations of the aquatic organisms. The water quality is becoming an ever-growing concern, and that is because of the human activity. If the water gets polluted, or eutrophicized, the marine life will very quickly die out and leave empty waters behind it.

Answer 2

D because some fish cannot adapt to changes in an environment fast enough, some fish carry diseases that can spread and kill many species and water quality because water purity is important so they are less likely to catch diseases from bacterial water
