Why would you not expect to find any photosynthetic organisms in the aphotic zone of a lake?
Delicious77 [7]

Answer:

There is little to no sunlight in the aphotic zone.

Explanation:

The aphotic zone is the deepest part of a lake/ocean, so no light is able to penetrate into those depths. Without light, photosynthetic organisms will not be able to undergo photosynthesis and will therefore not be able to survive.
