Why is benthic pelagic coupling important?

Benthic-pelagic coupling is manifested as the exchange of energy, mass, or nutrients between benthic and pelagic habitats. It plays a prominent role in aquatic ecosystems, and it is crucial to functions from nutrient cycling to energy transfer in food webs.

What is benthic planktonic coupling?

Benthic–pelagic coupling is a concept in which sea floor processes affect pelagic ecosystems (Rowe et al., 1975). It involves several oceanographic processes related to the chemistry, biology, and physics that actively link sea floor (benthos) with the overlying water masses (pelagos) (Fig. 1).

What do the terms benthic and pelagic mean?

The first major distinction is between 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.

How are pelagic and benthic organisms different?

The main difference between benthic and pelagic is that the benthic means relating to/occurring at the bottom of a body of water while pelagic means relating to/living or occurring in the open sea. Furthermore, benthic regions can be colder and darker while pelagic regions are lighter and warmer.

What is meant by benthic?

Definition of benthic

1 : of, relating to, or occurring at the bottom of a body of water. 2 : of, relating to, or occurring in the depths of the ocean.

What is the dominant role of benthic zone?

Benthic habitats play a critical role in the breakdown of organic matter, through the actions of scavengers, deposit-feeders, and bacteria. Most of the benthic habitats are in deep, pressured areas of the ocean.

What are benthic primary producers?

This spatially resolved modelling revealed that benthic primary producers (microphytobenthos) are the most important energy source for the majority of consumers at higher trophic levels (worms, molluscs, crustaceans, fish, and birds), and thus to the whole food web.

What is the benthic layer in an aquatic biome?

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.

Are mussels benthic?

Mussel biodeposits are a nutrient rich and easily assimilated food source and therefore may have significant relevance to benthic community structure. ... Mean fine benthic matter (organic and inorganic) collected from the bucket isolation experiment for the mussel (a), sediment (b) and control (c) treatments.

What does pelagic refer to?

Definition of pelagic

: of, relating to, or living or occurring in the open sea : oceanic pelagic sediment pelagic birds.

What are the 5 pelagic zones?

The pelagic zone is divided into epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadopelagic zones.

How is pelagic sediment formed?

Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. ... The second factor is water depth, which affects the preservation of both siliceous and calcareous biogenic particles as they settle to the ocean bottom.

Are crabs pelagic or benthic?

Adult crabs are primarily benthic creatures and live on the bottom of the Bay. Bay grass beds are very important for crabs because the young crabs use them for nursery areas and crabs of all sizes forage for food there. 9.

Is a Starfish benthic or pelagic?

The benthic zone is a sort of limbo area of the ocean. Deeper than the pelagic zone but not as deep as the dark abyssal zone, this zone is home to a rich population of algae, bacteria, sponges, sea stars and fish.

How is the benthic zone divided?

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 is another word for benthic?

In this page you can discover 17 synonyms, antonyms, idiomatic expressions, and related words for benthic, like: benthonic, benthal, zooplankton, macrofauna, macroinvertebrate, planktonic, foraminiferal, macrofaunal, macroinvertebrates, phytoplankton and subtidal.

What is a benthic community?

Benthic communities are largely composed of macroinvertebrates, such as annelids, mollusks, and crustaceans. These organisms inhabit the bottom substrates of estuaries and play a vital role in maintaining sediment and water quality.

What is the opposite of benthic?

Pelagic life decreases with increasing depth. The pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom of the sea. It includes the sediment surface and some subsurface layers.
