What is deep water ecosystem?

A deep sea community is any community of organisms associated by a shared habitat in the deep sea. … The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.

What type of ecosystem is the deep sea?

Marine ecosystems are aquatic environments with high levels of dissolved salt. These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which have different physical and biological characteristics.

Where is the deep sea ecosystem located?

The deep sea floor represents the largest habitat on earth. It ranges from the edge of the continental shelf at about 200m depth to the bottom of the ocean. At the edge of the continental shelf is the shelf break, where the gradient of the floor increases down the continental slope.

What are the main features of a deep ocean ecosystem?

Physical Characteristics of the Deep Sea

  • abiotic (non-living) ones, namely light (or lack thereof), pressure, currents, temperature, oxygen, nutrients and other chemicals; and.
  • biotic ones, that is, other organisms that may be potential predators, food, mates, competitors or symbionts.

Why is the deep sea ecosystem important?

The deep ocean is critical for the maintenance of the Earth’s climate. … Warmer water is not able to hold as much oxygen as cold water; so as the ocean warms, it also loses oxygen. Sequestering carbon in the deep sea is being explored to help reduce carbon in the atmosphere.

Which algae is found in deepest water?

Red algae are able to grow in depth of seas as compared to green algae because of the presence of more quantity of pigment phycoerythrin in red algae growing at depth.

What plants are in the deep sea?

Deep Ocean Plants

  • Red Algae Seaweeds. More than 2,000 species of red algae seaweeds can be found in the ocean. …
  • Phytoplankton. Phytoplankton rely on sunlight to photosynthesize, so they are generally found in shallower ocean waters. …
  • Sea Grasses. …
  • Bacteria.

What organisms live in the deep sea?

What is considered a deep ocean?

The deep ocean is generally defined as the depth at which light begins to dwindle, typically around 200 meters (656 feet). … Ocean depths greater than 1,000 meters (3,280 feet) are completely devoid of light and photosynthesis does not take place.

How does deep ocean affect the environment?

The Deep Sea plays a major role in climate change mitigation. By storing a large part of the CO2 produced by human activities and by absorbing the heat accumulated by greenhouse effect, the Deep Sea slows down the warming of surface waters and land. … In addition, Deep Sea ecosystems capture huge quantities of carbon.

How is global warming affecting the deep ocean?

The authors point out that global climate change could affect the food supply to the deep sea in many ways. Some relevant ocean processes that may be affected by climate change include wind-driven upwelling, the depth of mixing of the surface waters, and the delivery of nutrients to surface waters via dust storms.

How does the deep sea benefit humans?

It is vast, dark, remote and much of it is inaccessible to humans, so it has received less attention than other environments. But the deep sea represents 98.5 percent of the volume of our planet that is hospitable to animals and has vital global functions including sequestration of carbon from the atmosphere.
