What are the vertical stratification of aquatic and terrestrail?

In aquatic ecosystems, vertical stratification refers to the division of the water column into zones based on factors like light penetration, temperature, and nutrient availability. The zones typically include the epipelagic (surface), mesopelagic (twilight), and bathypelagic (midnight) zones. In terrestrial ecosystems, vertical stratification refers to the division of the environment into distinct layers such as the canopy, understory, shrub layer, herb layer, and forest floor, each of which supports specific plant and animal communities.
