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.
Why do some habitats support higher biodiversity than others?
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 …
Which habitat has more biodiversity?
There is more biodiversity within tropical ecosystems than temperate or boreal ecosystems. In fact, tropical rain forests have the most diversity.
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.
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.
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.
Habitat destruction renders entire habitats functionally unable to support the species present; biodiversity is reduced in this process when existing organisms in the habitat are displaced or destroyed. … The primary cause of species extinction worldwide is habitat destruction.
Which species has most diversity?
The sponges, Poriferans, were found to have some of the greatest diversity of both body size and species, ranging from microscopic to the size of an automobile. Molluscs (snails, squid, clams, chitons), and Arthropods (crabs, insects, lobsters, copepods) also showed great diversity.
What increases biodiversity?
As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance.
Is high biodiversity more advantageous than low biodiversity?
High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be…
Which regions have high levels of biodiversity?
Some areas in the world, such as areas of Mexico, South Africa, Brazil, the southwestern United States, and Madagascar, have more biodiversity than others. Areas with extremely high levels of biodiversity are called hotspots.
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.
