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.
The photic zone (also known as the euphotic zone) is the name for the depth of water, be it in lake, sea or ocean, which is exposed to sufficient sunlight to allow photosynthesis to take place. It extends from the Atmosphere-ocean interface downward to a depth where the light intensity is 1% of that at the surface. Its exact depth is dependent, therefore, on the extent of the light reduction within that water column, or in other words, it depends on how transparent the water is. The depth of the Photic zome typically ranges from only a few centimetres, normally in muddy, nutrient rich lakes, to around 200 meters, normally a depth found in the open ocean.
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.
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.
yes
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.
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.
I dont know i want to know the answer myself
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.
That is the photic zone, or euphotice zone.
photic zone.
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.
The photic zone of the ocean is the surface of the ocean that receives sunlight.
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
surface mixed zone , transition zone, deep zone
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.
Photic = where there's light Aphotic = where there isn't light, deeper waters.
The epipelagic zone is the region in the ocean that is exposed to a sufficient enough amount of sunlight to allow photosynthesis to occur.
