Photic - light; photic zone - light falling zone.
Depth of photic zone refers to the distance travelled by sunlight in to the depth of the water and enable photosynthesis. It is measured using SECCHI DISC or photometer.
Depth of photic zone is influenced by turbidity.
It includes atmosphere-water surface to the depth where the total penetrating light intensity falls by 1%.
This zone is a zone of productivity.
What else can I help you with?
Which marine biome is characterized by deep water depths that never receive sunlight?
The aphotic zone, also known as the midnight zone, is a marine biome characterized by deep water depths that never receive sunlight. This zone is found below the photic zone and is inhabited by organisms that do not rely on photosynthesis for energy.
What are 2 natural resources in the photic zone?
Two natural resources found in the photic zone are sunlight and nutrients. Sunlight is essential for photosynthesis, which provides energy for many organisms in this zone. Nutrients such as nitrogen and phosphorus are vital for the growth and productivity of plants and algae in the photic zone.
Do any abyssal zone animals go to the photic zone?
yes
The permanetly dark zone below the photic zone is called the?
The permanently dark zone below the photic zone is called the aphotic zone. In this region, sunlight is unable to penetrate deep enough for photosynthesis to occur, resulting in a lack of primary production by plants. Organisms in this zone rely on alternative energy sources, such as detritus and chemosynthesis.
Is the photic zone in the marine and freshwater ecosystems?
Yes, the photic zone is present in both marine and freshwater ecosystems. It refers to the region in a body of water where there is enough sunlight for photosynthesis to occur, typically extending to a few hundred meters deep in clear waters. This zone is important for supporting primary producers and the base of the food web in aquatic environments.
Portion of the marine biome that is too deep for sunlight to penetrate?
I dont know i want to know the answer myself
What type of animals live in the photic zone?
The uppermost layer of the world's oceans that receive sunlight during the daytime is called the photic zone. The depth of this zone depends on the clarity or murkiness of the water. In clear water, the photic zone can be quite deep; in murky water, it can be only 50 feet deep. On average, it extends to about 660 feet. Animals that live in the photic zone are plants, such as free-floating algae, sea weeds, etc. Zooplankton, most ocean fish, sea turtles, seals, etc. Bottom-dwellers such as starfish and sea shells live in the photic zone too. This zone is defined in terms of light, not depth.
What zone known as the sunlit zone stretches from the surface of the ocean down to 260 feet deep?
That is the photic zone, or euphotice zone.
What is the well lit upper layer part of the ocean is known as the?
photic zone.
How are organisms in the photic and aphotic zones interdependent?
The organisms in the aphotic zone depend on the organisms in the photic zone above to die, then drift down into the deep to provide food for the organisms down in the deep. I believe that the dependence of the photic organisms upon the aphotic organisms has to do with the necessity of breaking down the biomaterials and recycling the nutrients back into the system.
What is the photic zone of the ocean-?
The photic zone of the ocean is the surface of the ocean that receives sunlight.
What point in this body of water is most likely to be in the photic zone?
The photic zone is the upper layer of a body of water where sunlight penetrates, allowing photosynthesis to occur. This zone typically extends to about 200 meters deep in the ocean, depending on water clarity. In lakes and rivers, the photic zone is often much shallower, generally limited to the top few meters. Therefore, the point in the body of water closest to the surface is most likely to be in the photic zone.
In what ocean zone does the dolphin live in?
dolphins live in the pelagic zone (from shore to shore) and the Nerittic Zone (above continental shelf) and the photic zone (200m deep, where light penetrates) the are not found deeper than the photic zone
How do chemoautotrophs increase productivity in photic and aphotic ecosystems?
Chemoautotrophs do not increase productivity in photic zones because they reside deep down on sea floors (abyssal zone) where no light penetrates. They are, however, active in the aphotic zone where no light from the sun is visible. There, these bacteria and protozoans take both organic and inorganic compounds provided by deep sea vents and become the "algae of the photic zone". Chemoautotrophs are the primary producers in the lower aphotic zone just like algae and phytoplankton is in the photic. The vital nutrients they provide depend on the type of chemoautotroph it is.
What are three main zones of the open oceans?
surface mixed zone , transition zone, deep zone
What factors may affect the depth of the photic zone in any given area of the oceans?
The depth of the photic zone in the oceans is influenced by several factors, including water clarity, which is affected by the presence of phytoplankton, sediments, and dissolved organic matter. Additionally, the angle of sunlight, which varies with latitude and season, plays a crucial role in determining how deep light penetrates the water. Other factors include water temperature and salinity, which can affect the stratification of the water column and thereby influence light distribution. Lastly, ocean currents and wave action can also impact the mixing of surface waters, further affecting the depth of the photic zone.
What distinguishes the photic zone from the aphotic zone in an aquatic zone?
Photic = where there's light Aphotic = where there isn't light, deeper waters.
