The area on Earth considered to have the greatest biodiversity is the Tropical Andes region covering 1,258,000 km² (485,716 miles²) and running through Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and a small area of northern Argentina.

What has the greatest biodiversity?

The tropical rainforest biome has the greatest biodiversity. This biome has the most species of any other, and high numbers of most species.

What places most likely have low 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.

What is a community with high biodiversity?

High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.

Which community has least biodiverse?

The tundra is the biome with the least biodiversity.

Which continent has less biodiversity?

Originally Answered: Why Europe is the continent with the least biodiversity compared to Africa, Asia, the Americas and Oceania? Higher latitude cooler climate less cold blodded animals. But Europe does have the most Biodiverse cave so far.

What ecosystem has the highest biodiversity?

Two of the Most Diverse Ecosystems on Earth Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Which has more biodiversity a rainforest or a desert?

Both biomes have warm climates, but the desert is very dry, and the rainforest is very wet. The desert has very few organisms, so it has low biodiversity. … In contrast, the rainforest has the highest biodiversity of any biome on Earth.

Which biome has the highest biodiversity lowest?

Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.

Why is most biodiversity near the equator?

There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.

Article first time published on

Why some areas have higher biodiversity?

Unique Climates and Conditions. One of the most significant and naturally occurring causes of differences in biodiversity across the world is differences in climate. … On the other extreme, moist, tropical zones like the Amazon rainforest support some of the highest levels of biodiversity in the world.

Which continent has the highest diversity in terms of natural regions?

Asia, the world’s largest and most diverse continent.

Which layer of the ocean has the greatest biodiversity?

The epipelagic zone stretches from the surface down to 200 m and is home to the greatest biodiversity in the sea, largely because of the availability of sunlight that enables photosynthetic organisms to thrive. Both marine plants and animals are found here.

Is there more biodiversity on Earth near the equator or pole?

Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.

Which biome has the greatest biological diversity quizlet?

What is the definition of biodiversity? Which biome has the most biodiversity? the rainforest because it is located near the equator and has a perfect climate for a variety of organisms.

What biome in North America has the lowest biodiversity?

The biome in North America that has the lowest biodiversity is the Arctic tundra biome.

Why does the tropical rainforest have the greatest biodiversity?

Explanation: The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.

Which is more advantageous low or high biodiversity Why?

High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be…

Where do most species exist on the planet?

The question has held for the two decades since, even as humans have explored more and more of the deep ocean. Scientists now estimate that 80 percent of Earth’s species live on land, 15 percent in the ocean, and the remaining 5 percent in freshwater.

What is the greatest threat to biodiversity?

The greatest of all threats to Earth’s biodiversity, however, is deforestation. While deforestation threatens ecosystems across the globe, it’s particularly destructive to tropical rainforests.

What is the greatest threat to most species?

Habitat loss is probably the greatest threat to the variety of life on this planet today. It is identified as a main threat to 85% of all species described in the IUCN’s Red List (those species officially classified as “Threatened” and “Endangered”).

Do some habitats support more biodiversity than others?

The size of a habitat is another factor in the great diversity of the rainforest. Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.

Why does Ecuador have high biodiversity?

Ecuador is one of the 17 megadiverse countries of the world. This diversity is due to the location of the country in the neotropics, the presence of the Andes and the influence of the ocean’s currents on its coasts.

What is an example of high biodiversity?

Examples of places with high biodiversity include rainforests and coral reefs, because they have many different species in an area. Less biodiverse areas include deserts, icy areas, and the bottom of the ocean. Organisms do exist in those places, but not as many as places with higher biodiversity.

Which natural region occupies the largest area in the world?

Asia is the largest of the world’s continents, covering approximately 30 percent of the Earth’s land area.

Why is Asia called the continent of diversity?

Asian people differ in all aspects. Asia is called the continent of diversity and contrast because each people in the region doesn’t share the same culture, government, religion, races, ideas and etc. Asia is one of the world’s seven continents. It is the world’s most populated continent.

Which natural region occupies the largest area in the world taiga?

Which natural region occupies the largest area in the world. Answer: Taiga region occupies the largest area in the world.

Where would you find the greatest biodiversity in a marine environment?

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 zone has the greatest biodiversity apes?

For most terrestrial plants and animals, species diversity is highest in the tropics and declines as we move toward the poles. Most species-rich environments are tropical rain forests, large tropical lakes, coral reefs, and the ocean-bottom zone.

Where is greater biodiversity found?

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.

Why is there less diversity at the poles?

Any organisms in the poles must be able to withstand a cold, harsh climate. There are much less diverse food chains and webs that exist in these locations. Climate is a big factor in determining which biomes on the planet have greater biodiversity.
