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.
What supports high biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
Which has the greatest biodiversity?
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.
Which of the following environments would you expect to have the most biodiversity?
Worldwide, the tropics contain the most biodiversity, with rainforests being the areas that are the most rich in species.
What place 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.
Where can we find the greatest biodiversity on Earth?
Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
Which region of the Earth has the greatest biodiversity on Earth?
Amazon rain forest has the greatest biodiversity on planet.
Where can one find the greatest biodiversity on Earth *?
#1: Brazil. Brazil is the Earth’s biodiversity champion.
Which country supports almost 10% of biodiversity on Earth?
South Africa. One of the most diverse countries in the world. It contains nearly 10% of all known species of birds, fish and plants registered in the world and 6% of mammal and reptile species.
Which of the following is the most important cause for the loss of biodiversity?
-The main reason for the decrease in biodiversity is overpopulation, global warming, deforestation, and pollution. -The major biodiversity reducing factor is habitat destruction.
Which among the organism on earth has the greatest number identified or named?
In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
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.
Why is the most biodiversity found 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 factor affects biodiversity the most?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
