What are the 4 ocean zones?

Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.

Likewise What are the 4 layers of the ocean? Oceanographers generally categorize the ocean into four layers: the epipelagic zone, the mesopelagic zone, the bathypelagic zone, and the abyssopelagic zone.

What would we call a phytoplankton? Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.

Also What are the 3 horizontal ocean zones?

The ocean is divided into horizontal zones based on the distance from shore and the depth of water beneath: the intertidal, neritic, and oceanic.

What is ocean zonation?

zonation-describes the different zones or areas of the marine environment. distribution-describes where animals live within these zones. pelagic-all waters of the ocean. benthic-extends from the intertidal, to the continental shelf, to the continental slope, to the deep. ocean floor.

How many levels are in the ocean? Scientists have divided the ocean into five main layers. These layers, known as “zones”, extend from the surface to the most extreme depths where light can no longer penetrate.

What is the top layer of the ocean called? The top surface layer is called the epipelagic zone, and is sometimes referred to as the “ocean skin” or “sunlight zone.” This layer interacts with the wind and waves, which mixes the water and distributes the warmth.

What is zooplankton scientific name? Noctiluca. scintillans. Plankton is composed of the phytoplankton (“the plants of the sea”) and zooplankton (zoh-plankton) which are typically the tiny animals found near the surface in aquatic environments.

What animal is plankton from Spongebob?

Did you know that the character Plankton from Spongebob is based on a real planktonic animal – the Copepod (shown above)? There are even specific group of copepods with one eye, just like Plankton, called Cyclops!

What is killing phytoplankton? UV from sunlight excites nanoparticles to kill phytoplankton in lab setting. … Phytoplankton are very small marine organisms (most are too small to be seen with the unaided eye) that regulate the global climate by taking up vast quantities of carbon dioxide, or CO2, from the atmosphere via photosynthesis.

What is the abyss in the ocean?

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. “Abyss” derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness. … The area below the abyssal zone is the sparsely inhabited hadal zone.

How deep is the Mariana Trench? It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level. Show students NOAA’s Mariana Trench animation.

Where is the pelagic zone?

The pelagic zone is the part of the open sea or ocean comprising the water column, i.e., all of the sea other than that near the coast or the sea floor. In contrast, the demersal zone comprises the water that is near to (and is significantly affected by) the coast or the sea floor.

How deep is the Twilight Zone?

The zone between 200 meters and 1,000 meters is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases.

What are the oceanic divisions? The major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria: these divisions are (in descending order of size) the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean (which is sometimes subsumed as the southern portions of the Pacific, Atlantic, and …

What is the open ocean called? The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas. … Epipelagic zone (ocean surface to 200 meters deep). This is the zone in which photosynthesis can occur, because light is available.

How deep is the twilight zone?

The zone between 200 meters and 1,000 meters is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases.

What is an abyss in the ocean? abyssal zone, portion of the ocean deeper than about 2,000 m (6,600 feet) and shallower than about 6,000 m (20,000 feet). The zone is defined mainly by its extremely uniform environmental conditions, as reflected in the distinct life forms inhabiting it.

Is a jellyfish a zooplankton?

Jellyfish are a type of zooplankton that both drift in the ocean and have some swimming ability. Hundreds of jellyfish species live in every part of the ocean and belong to the same animal group as corals and sea anemones.

Is krill a zooplankton? Krill are amongst the largest and most ecologically important zooplankton and they feed on phytoplankton.

Can you see zooplankton?

Lakes and streams are teeming with life but most of these organisms cannot be seen with the naked eye. If you haul a very fine-meshed net through the water, tip your catch into a jar and hold it up to the light, you may see some of the larger species of zooplankton swimming jerkily up and down.

Is plankton a cockroach? Cockroaches are mentioned and referenced in various other episodes. In “Plankton’s Army,” Plankton disguises himself as a cockroach. In “Ghost Host,” the Flying Dutchman turns into a giant cockroach.
