What are the 5 zones of the benthic environment?

The benthic environment is divided into a number of distinctive ecological zones based on depth, seafloor topography, and vertical gradients of physical parameters. These are the supralittoral, littoral, sublittoral, bathyal, abyssal, and hadal zones.

What are benthic environments?

Page 1. The benthic zone is the ecological region at the lowest level of a body of water. It starts at the shoreline and continues down until it reaches the floor, encompassing the sediment surface and sub- surface layers. Although this zone may appear barren, it plays a vital role in the health of aquatic ecosystems.

What are the different layers of the benthic zone?

From the shallowest to the deepest are: the epipelagic (less than 200 meters), the mesopelagic (200–1,000 meters), the bathyal (1,000–4,000 meters), the abyssal (4,000–6,000 meters) and the deepest, the hadal (below 6,000 meters). The lower zones are in deep, pressurized areas of the ocean.

What are part of the benthic community?

The word benthos comes from a Greek term meaning “depths of the sea.” Benthic communities are complex and include a wide range of animals, plants and bacteria from all levels of the food web. Clams, worms, oysters, shrimp-like crustaceans and mussels are all examples of benthic organisms.

What is common to all of the benthic zones?

Nutrient availability in the deep sea is also scarce, so organisms need to adapt themselves accordingly to survive here. Organisms living in the benthic zone are called benthos. Benthos have specially adapted themselves to live on the bottom substrate in deep-water bodies with elevated pressure and cold temperatures.

Where is the benthic zone?

The benthic zone is the lowest ecological zone in a water body, and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.

What does the benthic zone look like?

The benthic zone is the lowest level of a marine or freshwater system and includes the sediment surface, the water just above it, and some sub-surface layers. ... Because of the depths it can reach, the benthic zone is often characterized by low sunlight and low temperatures (Alldredge 1988).

What are the three zones in the benthic environment?

The benthic zone is subdivided into different zones, namely intertidal or littoral zone, supralittoral zone, sublittoral zone, bathyal zone, abyssal zone and hadal zone.

What five zones make up the oceanic zone?

The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the ...

What are the pelagic and benthic zones?

The pelagic zone refers to the water column, where swimming and floating organisms live. The benthic zone refers to the bottom, and organisms living on and in the bottom are known as the benthos .

Why do most marine species inhabit the benthic environment?

Of all marine species, 98% live on or in the ocean floor. These organisms are called benthos, or bottom dwellers. ... Because light does not penetrate very deep ocean-water, the energy source for the benthic ecosystem is often organic matter from higher up in the water column which drifts down to the depths.

Why are more species found in the benthic environment compared to the pelagic environment?

In the ocean, the benthic environment has many habitats, or niches, for organisms. Therefore the benthic environment can support more species due to more niches, or specialized habitats, for a wider variety of organisms than the fairly uniform open waters of the pelagic environment.

Where are intertidal zones located in the world?

The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

Is Coral a benthic?

3.1 Coral Reef Ecosystem. Coral reefs are archetypical benthic ecosystem found in warm, oligotrophic, shallow depth in tropical waters.

Are coral reefs in the benthic zone?

Coral Reefs and Benthic Life Forms

The superficial layer of the soil lining the given body of water is an integral part of the benthic zone, as it influences greatly the biological activity which takes place there. Examples of contact soil layers include sand bottoms, rock outcrops, coral, and bay mud.

What is a marine benthic ecosystem?

4.1 Benthic Marine. Definition: Those marine ecosystems consisting of organisms living on, attached to, or burrowing in the sediment of the ocean floor.
