Question

Quizplus · Accepted Answer

A lake would possess a photic layer, which is the upper layer of water where light can penetrate and photosynthesis can occur.

The other choices are not applicable to lakes specifically. A canopy typically refers to the upper layer of trees in a forest, not a body of water. A herb layer is a term used in ecology to describe the layer of ground vegetation in a forest or other habitat, again not relevant to a lake. Keystone species refers to a species that has a disproportionately large effect on an ecosystem, which could include lakes but is not a physical structure of the lake itself.
