In all, the Arctic is home to more than 21,000 known species of highly cold-adapted mammals, birds, fish, invertebrates, plants and fungi and microbe species. This extensive biodiversity provides essential services and values to people.
Where is biodiversity the highest?
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.
Does the Arctic tundra have high biodiversity?
The biodiversity of the tundras is low: 1,700 species of flora and only 48 land mammals can be found, although thousands of insects and birds migrate there each year for the marshes.
How much biodiversity is in the Arctic Ocean?
The currently known Arctic species richness estimate includes close to 2,000 phytoplankton taxa, over 1,000 ice-associated protists, greater than 50 ice-associated metazoans, ~ 350 multicellular zooplankton species, over 4,500 benthic protozoans and invertebrates, at least 160 macro-algae, 243 fishes, 64 seabirds, and …
What climate has the most biodiversity?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
Which ecosystem has high biodiversity low biodiversity?
Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts, for example, contain limited numbers of species.
What biome in North America has the highest biodiversity?
The biome that has the highest biodiversity in North America is the tropical rain forests.
Does the desert have high or low biodiversity?
Whether hot or cold, the biodiversity of the desert is very low. In a hot desert environment, plants consist primarily of cacti. In a cold desert, mosses, lichens and fungi are found.
What kind of ecosystem is in the Arctic?
The Arctic consists of taiga (or boreal forest) and tundra biomes, which also dominate very high elevations, even in the tropics. Sensitive ecosystems exist throughout the Arctic region, which are being impacted dramatically by global warming.
What is the Arctic ecosystem?
The Arctic is a unique ecosystem with a complex food web made up of organisms adapted to its extreme conditions. It is one of the most biologically productive ecosystems in the world, supporting many large fisheries and huge populations of migratory birds that come to the Arctic in the summer to breed.
Why is the Arctic ecosystem important?
The Arctic is crucial for lots of reasons. Not just because it’s home to the iconic polar bear, and four million people, but also because it helps keep our world’s climate in balance. … The Arctic also helps circulate the world’s ocean currents, moving cold and warm water around the globe.
Why do warmer climates have greater biodiversity?
Sample Response: Warm climates allow for a year-round growing season. Plants are more available as a food resource, which can support more organisms. … Warm climates allow for a year-round growing season. More availability of plants provides more food resources for a greater number of organisms.
Which climate supports more diverse vegetation?
Tropical rainforests, which worldwide make up one of Earth’s largest biomes (major life zones), are dominated by broad-leaved trees that form a dense upper canopy (layer of foliage) and contain a diverse array of vegetation and other life.
Which ecosystem most likely has the greatest biological diversity and therefore the highest sustainability?
Tropical rain forest have the greatest biodiversity of any type of land ecosystem.
