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.
Where is biodiversity the greatest on Earth?
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.
Why is biodiversity greatest at 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.
Where is there more biodiversity and why?
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 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.
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).
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.
Why is there greater biodiversity in the tropics?
– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.
Why is biodiversity so much greater in the tropics than in higher latitudes?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
Which region has greatest diversity?
Species diversity is greatest in the tropics, particularly in tropical forests and coral reefs. The Amazon basin in South America has the largest area of tropical forests.
Which of the following countries has highest biodiversity?
Brazil is the only country with highest biodiversity. Biodiversity accounts one-tenth of the world’s overall species.
How biodiversity is distributed on Earth?
Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species.
Which state probably has the greatest biodiversity?
- California. The richness of California’s flora makes it a biodiversity hotspot even in global comparisons. …
- Texas. Like in California, the species richness in Texas comes from the state’s sheer size and the variety of ecosystems present. …
- Arizona. …
- New Mexico. …
