Which of the following statements accurately describes the "photic zone" and "aphotic zone" in aquatic environments?

  • option_A: The photic zone is the region where there is sufficient light for photosynthesis, while the aphotic zone is the region where little light penetrates.
  • option_B: The photic zone is the deepest part of the aquatic environment, and the aphotic zone is located near the surface.
  • option_C: Both the photic and aphotic zones are primarily characterized by high salt concentration, regardless of light levels.
  • option_D: The photic zone primarily contains benthos, while the aphotic zone is where nekton are predominantly found.

Explanation

The text clearly defines the photic zone as the region with sufficient light for photosynthesis and the aphotic zone as the region where little light penetrates. These definitions are based on light availability.
