Question

question 5 (multiple choice worth 3 points)
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.
it would thrive, because water currents would carry it far from the shore
it would thrive, because more nutrients are available deeper in the ocean
it would die, because sunlight is unable to penetrate deep into the ocean
it would die, because there are lower oxygen levels in deep zones of the ocean

Explanation:

Atlantic halibut uses gills to extract dissolved gases (like oxygen) from water. In deep - ocean zones, oxygen levels are lower. Cellular respiration requires oxygen. If there is not enough oxygen (due to being in a deep - ocean layer with low oxygen), the halibut population would not be able to carry out cellular respiration effectively. Being carried far from the shore does not directly relate to its survival mechanism (gill - based gas extraction for respiration). Nutrients are not the key factor for its respiration - based survival. Sunlight is not relevant to its gas - extraction - based cellular respiration.

Answer:

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