What are the 3 zones in the ocean?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What is an example of neritic zone?
The neritic zones in tropical climates, like the Great Barrier Reef in Australia, are home to thousands of species of sea life, such as coral, sharks, and sea snakes that are found nowhere else in the world. Northern neritic zones are also flourishing with sea life, including sea otters, whales, and the giant octopus.
What is below the sublittoral zone?
The intertidal zone is located between high and low tides. The sublittoral zone is always underwater and is below the low tide line. This zone extends all the way to where the continental shelf drops off into the abyssal plane. Everything except areas near the coast and the sea floor is called the pelagic zone.
Which zone is the most productive?
Vertically, the pelagic realm can be subdivided into 5 more zones. The uppermost zone, from the sea surface to a depth of 200 m (656 ft), is called the epipelagic or photic zone. The large amount of available sunlight makes this the most productive zone of the ocean.
What do you mean by the neritic zone?
Neritic zone. Written By: Neritic zone, shallow marine environment extending from mean low water down to 200-metre (660-foot) depths, generally corresponding to the continental shelf.
Where is the neritic zone on the continental shelf?
The neritic zone (“near shore”) extends from the high tide mark to the edge of the continental shelf. Thus, it is the shallow water zone on the continental shelf. The biotic communities of the neritic zone consist of the following groups.
What are the marine habitats in the neritic zone?
Neritic zone. Marine habitats. Sargassum seaweed drifting in the neritic zone provides food and shelter for small epipelagic fish. The neritic zone is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately 200 meters (660 ft) in depth.
Which is the dominant producer in the neritic zone?
The dominant producers in the neritic zone are passively drifting or floating algae, called phytoplankton, although in some locations the algae attached to the bottom also become important as producers. Most of the algal types included in the phytoplankton are microscopic.
