What is deep sea 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 is marine ecosystem PDF?
The habitats of the open seas and adjacent coastal zones are classified under marine ecosystems. In addition to these, marine ecosystems also include the salt marshes and wetlands located along the shores and river mouths. Such zones including estuaries contain the habitat of both freshwater and salt water.
What type of ecosystem is the ocean?
Marine ecosystems
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.
What is the deepest ecosystem?
The abyssal plain ecosystem is the largest ecosystem on Earth. It lies beyond the continental slope, between 3,000 and 6,000 m depth. Abyssal plains are covered by a thick layer of fine sediment that can reach thousands of metres in thickness, resulting in the popular picture of a flat, monotonous deep-sea bed.
What is inside the deep ocean?
The abyssal plain is the relatively level deep seafloor. It is a cold and dark place that lies between 3,000 and 6,000 meters below the sea surface. It is also home to squat lobsters, red prawns, and various species of sea cucumbers. For these creatures food is scarce most of the time.
Which aquatic ecosystem is the deepest?
Oceans are the largest of the ecosystems, covering more than 70 percent of the Earth’s surface. The ocean ecosystem is divided into four distinct zones. The deepest zone of this marine ecosystem, the abyssal zone, has cold, highly-pressurized water with high oxygen but low nutrient levels.

Why marine ecosystem is important?
Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
What is the function of marine ecosystem?
Marine ecosystems also provide other important services, associated with their regulatory and habitat functions, such as pollution control, storm protection, flood control, habitat for species, and shoreline stabilization.
What is in a ocean ecosystem?
The ocean ecosystem includes everything in the oceans, as well as the saltwater bays, seas and inlets, the shorelines and salt marshes. It is home to the smallest organisms like plankton and bacteria, as well as the world’s largest living structure – the Great Barrier Reef, which can even be seen from the moon.
