Question

Atlantic halibut is a species of flatfish that uses gills to extract dissolved gases from water for cellular respiration. During a storm, a population of halibut is carried down into a deeper layer of the ocean. Predict whether this population would most likely thrive or die, and select the best explanation.

Answer 1

The population of fish would slowly begin to die out as the deeper the water the less dissolved gasses there are.

Answer 2

Answer:

D. It would die, because there are lower oxygen levels in deep zones of the ocean.

The deeper the ocean, the less gas exchange there is.
