Question

Quizplus · Accepted Answer

The aphotic zone of the ocean is the part which does not receive any sunlight. Therefore, photosynthesis cannot occur, and the primary production (or energy) for this zone comes from the organic matter that sinks down from the photic zone above, i.e., A. Option B and C are not possible as there is no sunlight, so no photosynthesis can happen. Although sulfur bacteria can be found near hydrothermal vents, it is not the primary source of energy for the rest of the aphotic zone. So, option D is incorrect.
