Emphasising the aspects of species richness and abundance, biodiversity is overwhelmingly concentrated in the tropical ecosystems of rainforests, savannas, freshwater bodies and shallow-water coral reefs, where over three-quarters of all known non-marine species can be found.
Where the biodiversity is more?
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 do some places have more 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.
What parts of the Earth have the greatest biodiversity and why?
What part of the earth has the most biodiversity Why? 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.
Why is there more 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.
Which continent has the most biodiversity?
As a continent, America has the most biodiverse countries in the world. Brazil, Ecuador, Mexico, Venezuela, Colombia, Peru and the United States are the countries in this continent that have many different ecosystems and species.
What does higher biodiversity mean?
Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.
Why do some places so higher diversity than other?
There are at least three possible scenarios or “routes” that a region may follow to become a biodiversity hotspot: a region can have lots of species because it generates species at faster rates than nearby areas, or because they import species from their surroundings at faster rates (that is, they attract species), or …
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.
Is there more biodiversity on Earth near the equator or pole?
This pattern, called the latitudinal diversity gradient, has not always existed, new research finds. From plants to animals, insects to fish, mammals to reptiles, and vertebrates to invertebrates, there are generally more species at lower latitudes, closer to the equator, than at higher ones, closer to the poles.
Where is Earth’s greatest biodiversity quizlet?
Why is Earth’s biodiversity greatest near the equator? More species can live in warm climates than in cold climates.
In which forest the highest biodiversity is found?
The highest biodiversity is found in tropical rain forests.
Why is there higher biodiversity in the tropics?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
What kind of climate has a high biodiversity?
Tropical rainforests are the most biodiverse habitats on Earth. They are home to a huge number of different plants, animals, fungi and other organisms.
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.
