Which of the following marine ecosystem is the most productive one?

The answer is coral reef ecosystem .

Which marine biome is the most productive?

The aquatic biome with the highest level of primary productivity is the coral reef biome with around 2,500 grams of biomass per square meter per year. The biome that includes swamps and marshes and the estuary biome are the other aquatic biomes that have high levels of primary productivity.

Where are the most productive marine ecosystems found?

As a result, estuaries are among the most productive places on Earth and support many types of life. In addition, because they are located where rivers join the ocean, estuaries have traditionally supported many human communities and activities like fishing, shipping, and transportation.

What is the most important marine ecosystem?

The most important marine ecosystems for marine life are estuaries and coral reefs. These two marine ecosystems are important because the estuaries are breeding territories for many marine animals, because it is easy for young-lings to survive there, since there are no known predators that live in that region.

What are the 4 types of marine ecosystems?

Like oceans, lakes and ponds are divided into four distinct zones: littoral, limnetic, profundal and benthic.

Which freshwater ecosystem is the most productive?

Estuaries are among the most productive ecosystems in the world. Many animals rely on estuaries for food, places to breed, and migration stopovers.

Which is the most productive and biodiverse aquatic ecosystem?

The answer is coral reef ecosystem . More than 25% of marine flora and fauna live in this ecosystem, but corals occupy only 1% of the ocean floor.

Which is the most productive ecosystem?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What is marine productivity?

What is Ocean Productivity? Ocean productivity largely refers to the production of organic matter by “phytoplankton,” plants suspended in the ocean, most of which are single-celled. … “Secondary production” (SP) typically refers to the growth rate of heterotrophic biomass.

What is the productivity of aquatic ecosystem?

In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors. Primary productivity is important because it is the process that forms the foundation of food webs in most ecosystems.

Which of the following is example of marine ecosystem?

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. The ocean covers 71 percent of the planet, so marine ecosystems make up most of the Earth.

IMPORTANT:  What is one of the three scientific principles of environmental science?

Which is an example of a marine ecosystem?

Marine ecosystems include: the abyssal plain (areas like deep sea coral, whale falls, and brine pools), polar regions such as the Antarctic and Arctic, coral reefs, the deep sea (such as the community found in the abyssal water column), hydrothermal vents, kelp forests, mangroves, the open ocean, rocky shores, salt …

What is the importance of ocean ecosystem?

Oceans are an important source of food. They host 80 percent of the planet’s biodiversity, and are the largest ecosystem on Earth. Fish provide 20 percent of animal protein to about 3 billion people.

Why are estuaries very productive ecosystems?

Estuaries are very biologically productive. The salinity gradient and the changes in tides, fresh water and accompanying flux in nutrients within estuaries create a variety of habitats that support a diverse food web. … Because these gradients exist, estuaries are transition zones for many species of wildlife and fish.

How many marine ecosystems are there?

Globally, the world’s oceans have been divided into 66 large marine ecosystems (LMEs). These are defined as near coastal areas where primary productivity is generally higher than in open ocean areas.

How many aquatic marine ecosystems are there?

Water/Pelagic environment consists of two major marine ecosystems, Neritic and Oceanic zones. Bottom/Benthic environment consists of the other three major ecosystems, Supralittoral, Intertidal/Littoral, and Sublittoral zones. The major five marine ecosystems nurture almost half of the identified species on Earth.
