The diagram illustrates plants and two different zones of a deep lake.
In the upper part of the photic zone, organisms carry out both photosynthesis and cellular respiration. Deep in the aphotic zone, only cellular respiration occurs. Which statement is the most likely reason photosynthesis does not occur in the deepest aphotic zone?
Sunlight for photosynthesis does not reach the deepest aphotic zone. Rationale: The light intensity in the water generally decreases because of particles and even algae in the water blocking the light. This reduces the ability of plant life and algae to carry out photosynthesis.
Water pressure limits the survival of animals in the deepest aphotic zone. Rationale: Many animals can survive intense water pressure and animals do not perform photosynthesis.
Not enough soil is present to support plant growth in the deepest aphotic zone. Rationale: Sunlight, not soil, is the limiting factor in the aphotic zone.
Not as much dissolved oxygen from the surface reaches the deepest aphotic zone. Rationale: While this may be true, it would not interfere with photosynthesis.
