Does the ocean have the most biodiversity?
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.
What location on Earth has the most biodiversity?
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.
Is there more biodiversity in the ocean or on land?
It has long been known that there are far more species living on land than in the sea. Although the oceans cover a little >70% of Earth’s surface, they account for only a small fraction of nonmicrobial species, estimated at anywhere from 5% (Benton 2009) to 15% (May 1994). Most of the remaining species reside on land.
How much of Earth biodiversity is in the ocean?
Assessment of this pattern for all kingdoms of life on Earth predicts ∼8.7 million (±1.3 million SE) species globally, of which ∼2.2 million (±0.18 million SE) are marine. Our results suggest that some 86% of the species on Earth, and 91% in the ocean, still await description.
Where in the ocean has the most biodiversity?
The ocean contains a wealth of biodiversity, and most of this diversity lives in the sunlit area called the euphotic zone (see Distribution of Life, page 45, for more information).
Which sea has most biodiversity?
A new study finds that sea surface temperature, as well as the size and variety of habitats are the main factors responsible for the proliferation of marine life in the Coral Triangle – the most biologically diverse marine region in the world.
Where is the least biodiverse place on Earth?
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.
Which is the most biodiverse region in the world and why?
Brazil. It is the country with the greatest biodiversity of flora and fauna on the planet. Brazil has the highest number of species of known mammals and freshwater fish, and more than 50,000 species of trees and bushes, it takes first place in plant diversity.
Why is biodiversity so important in our oceans?
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 percentage of water and land on Earth?
71% of Earth is water while 29% is land. Both will serve, depending upon your need and aim. The interesting thing is that the percentage of water on Earth does not include only the obvious sources of water, like oceans and lakes, but less obvious sources as well.
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.
