Is the ocean high biodiversity?

The world’s oceans contain somewhere between 500,000 and 10 million marine species. … 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.

Does the ocean have a high or low biodiversity?

Ecosystems based upon water can either be highly diverse or have a very low biodiversity. The ecosystems that are marine, or made up of saltwater, include coral reefs and the intertidal zone, which are both highly diverse, as well as the open ocean, which has a fairly low biodiversity.

How much biodiversity is in the oceans?

Oceans cover 70% of our planet and represent over 95% of the biosphere.

Does the ocean have the most diversity?

Scientists estimate that 25 percent of all marine species live on coral reefs, making them one of the most diverse habitats in the world. Ocean life is not evenly distributed. Life in the euphotic zone is very diverse due to availability of sunlight and diversity of producers found in this zone.

Where is ocean biodiversity the highest?

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.

Why is the ocean high biodiversity?

` The marine environment has a very high biodiversity because 32 out of the 33 described animal phyla are represented in there.

What is ocean biodiversity?

Marine biodiversity therefore refers to the species richness and abundance in the world’s oceans and seas. And since the world is covered with approximately 70% water, the amount of life in the oceans is enormous. … Protection of water resources (e.g. Mangrove forests trap silt)

What is high biodiversity?

High biodiversity is a habitat or ecosystem that has a high number of different species.

Why is the ocean so diverse?

“The oceans we see today are filled with a dizzying array of species in groups like fishes, arthropods, and mollusks, not because they had higher origination rates than groups that are less common, but because they had lower extinction rates over very long intervals of time.”

What part of the ocean has the least biodiversity?

The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.

How does the ocean support diversity?

The ocean provides a vast living space with diverse and unique ecosystems from the surface, through the water column, and down to and below the seafloor. For example, coral organisms facilitate an exceptionally biodiverse ecosystem (Fig. 1.6).

How is the ocean home to the greatest 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.

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.
