Which of the following must be true about the organisms living in the aphotic zone?

Answer 1

Creatures in this area must be able to live in complete darkness and in close to freezing water. In the aphotic zone, there virtually no light from the sun (1% or less of sunlight reached this zone), so photosynthesis can not take place.
