The major five marine ecosystems nurture almost half of the identified species on Earth. The word marine refers to sea water and all plants and animals which are found in the seas. process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars. See more ideas about marine ecosystem, marine, plastic pollution. Giant tube worms, located in the hydrothermal vent ecosystem at 2,499 meters (8,200 feet) below the surface, have long, white bodies and no eyes, mouth, or stomach. In addition to these, marine ecosystems also include the salt marshes and wetlands located along the shores and river mouths.

The aquatic ecosystem is the habitat for water-dependent living … Nearshore marine ecosystems face significant challenges at global and regional scales, with threats arising from both the adjacent lands and oceans. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply and 90% of habitable space on Earth. National Geographic Headquarters The following chart shows the types of Natural Ecosystem − The Northwest Hawaiian Island coral reefs, which are part of the Papahānaumokuākea National Marine Monument, provide an example of the diversity of life associated with shallow-water reef ecosystems. Oceans, estuaries, coral reefs and coastal ecosystems are the various kinds of marine ecosystems. An ecosystem is defined as "a community and the interactions of living and nonliving things in an area." Sperm whales can dive more than 1.6 kilometers (one mile) below the surface of the water. Most vital exchange of gases for human survival is done by Marine Ecosystems. rocky ocean features made up of millions of coral skeletons. The algae and other intertidal plants grow in abundant sunlight and act as a food source for animals. Other physical factors that determine the distribution of marine ecosystems are geology, temperature, tides, light availability, and geography.Some marine ecosystems are very productive. community and interactions of living and nonliving things in an area. Join our community of educators and receive the latest information on National Geographic's resources for you and your students. Based on the types of marine ecosystems, a benthic environment can be classified into three categories: Supralittoral Zone – Also known as Splash Zone, this area lies above the high tide line on the coastlines and estuaries. It can be classified as either fresh water ecosystem or marine ecosystem. all the Earth's water in the ground, on the surface, and in the air. Water/Pelagic environment covers 1300 million km^3, consisting of open ocean. Male seahorses give birth, rather than female seahorses. Marine habitats are one of the largest and most biodiverse places on Earth. This region predominantly has high salt content gathered by the spray of tides. The depth of pelagic environment varies from 3.50 km (2.17 miles) to 11 km (6.83 miles). An aquatic ecosystem includes freshwater habitats like lakes, ponds, rivers, oceans and streams, wetlands, swamp, etc. The organisms that inhabit various marine ecosystems are as diverse as the ecosystems themselves. Low water pressure makes the plant and fish life to survive in this region. However, humans do create these boundaries for the sake of study and understanding. Two-thirds of the total surface area of the planet is covered by marine water. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water.. Lagoons are the shallow water body separated by reefs or barrier island from the large water bodies such as oceans. Marine ecosystems are one among the largest; the most prevalent aquatic ecosystems on Earth. Many marine life have an important role in the world such as the tiny plankton because without them the world would build up with carbon dioxide, the plankt… Like how we classify living things, with domains, classes, species, etc…, we also can consider ecosystems to be somethin… Since it is the largest biome in the world, the climate varies from -40 degrees fahreheit to over 100 degrees. coastal wetland that is flooded with seawater, often by tides. Many parts of the ocean remain unexplored and much still remains to be learned about marine ecosystems. mouth of a river where the river's current meets the sea's tide.

Zooplankton is eaten by small fish which are in turn eate… In some places the ocean is deeper than Mount Everest is high; for example, the Mariana Trench and the Tonga Trench in the western part of the Pacific Ocean reach Some marine ecosystems, like the deep sea, are in constant darkness where photosynthesis cannot occur. Benthos acts as a source of food to not just aquatic animals but humans too. coastal wetland formed as rivers or tides deposit sediment. It also gives those marine animals a place to hunt. (Freshwater ecosystems, on the other hand, are comprised of freshwater environments such as those in rivers or lakes. An example of a marine ecosystem is a coral reef, with its associated marine life — including fish and sea turtles — and the rocks and sand found in the area. Among the known species in marine ecosystems, Pelagic and Benthic environment sustains most of the life inside the oceans. Unlike the Intertidal zone, this region of the marine ecosystem is always submerged in water. The climate of the marine biome is mostly varied.
