The photic zone refers to an area of 200 m from the surface and is delimited by light penetrance. The photic zone is where Brian would show as containing autotrophic producers.
What are the photic and aphotic zones?
In aquatic environments, there is a variation of factors like temperature, light, salinity, nutrients, oxygen, and other factors.
According to these factors' variation, the mass of water can be divided into different vertical and horizontal strata.
Concerning light, penetrance occurs up to 200 meters deep from the surface. This depth is the máximum level of active photosynthetic radiation penetrance.
The photic zone is the area delimited by light penetrance. In this region, photosynthesis occurs hence, producers and most organisms can be found.
The aphotic zone is the area below the photic one and refers to the depths where light does not reach. These depths are superior to 200m.
The photic zone is where Brian would show as containing autotrophic producers.
