You asked: Which marine ecosystem is the most diverse?

The variety of species living on a coral reef is greater than in any other shallow-water marine ecosystem, making reefs one of the most diverse ecosystems on the planet. Covering less than one percent of the ocean floor, coral reefs support an estimated 25 percent of all known marine species.

Which part of the ocean is most diverse?

The Coral Triangle in Southeast Asia is the most diverse place in the ocean. And it could hold the secrets to protecting huge swathes of the planet’s underwater habitats.

What is the most diversified ecosystem?

Do you know that more than 40 percent of world’s animal and plant species live or breed in wetlands? This incredible figure makes wetlands the most biologically diverse ecosystem in the world.

Where is the most marine biodiversity?

The epipelagic zone extends from the surface to 200m down. It receives plenty of sunlight and therefore contains the most biodiversity in the ocean. Next comes the mesopelagic zone which extends from 200m to 1,000m. It is also called the twilight zone because of the limited light that can filter through these waters.

Why are marine animals more diverse?

Upending an evolutionary theory proposed in the 1950s, scientists have found that the groups most resistant to extinction also contain the greatest ecological diversity – their members perform a larger number of different functions in ecosystems.

Which best explains how the ocean is the most diverse ecosystem?

Which best explains how the ocean is the most diverse ecosystem? It receives nutrients from land carried by rivers and upwelling. … Light does not reach the bottom of the ocean, yet certain species live there.

Which species has most diversity?

The sponges, Poriferans, were found to have some of the greatest diversity of both body size and species, ranging from microscopic to the size of an automobile. Molluscs (snails, squid, clams, chitons), and Arthropods (crabs, insects, lobsters, copepods) also showed great diversity.

What is the examples of diverse ecosystem?

Grasslands, tundras, deserts, rainforests, terrestrial and marine ecosystems, are some examples of ecosystems that are diverse and contribute a lot to creating a well-balanced environment.

Which of the following has greatest species diversity?

Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.

How diverse is the ocean?

The world’s oceans contain somewhere between 500,000 and 10 million marine species. bacteria, other microbes and viruses. Much of the biodiversity in the ocean, particularly in the deep sea and in the microbial ocean, is unknown, and up to 2,000 new species are described per year.

How diverse is the deep-sea?

It is now accepted that the deep-sea has high diversity and it has been suggested that in the deep- sea there may be up to 10 million new species yet to be de- scribed (Grassle & Maciolek 1992; Am.

Why are freshwater ecosystems more diverse than marine ecosystems?

Organisms living in the terrestrial ecosystems are influenced far more by gravity, while water supports marine organisms. Locomotion for terrestrial organisms requires much more energy than do marine organisms just to escape from risks of predation.

Why are terrestrial ecosystems more diverse?

Terrestrial environments are generally far more physically complex, largely because of habitat provided by plants, both above and below ground. … This, in turn, provides far more habitat diversity over smaller spatial scales than exists in most marine environments.
