(i) More solar energy is available in tropics which promote higher productivity and increased biodiversity. (ii) There is no favourable season in tropics. Continued favourable environment has helped tropical organisms to gain more niche specialisation and increased diversity.
What are the reason for greater biodiversity?
Typically, biodiversity is a representation of variation at the level of biology, plants, and habitats. Closer to the equator, which is the outcome of the warm atmosphere and relatively high productivity, terrestrial biodiversity is typically greater.
What are 3 things that form biodiversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.
What are the reasons for greater biodiversity in the tropics?
(1) Tropical latitudes receive more solar energy than temperate regions, which leads to high productivity and high species diversity. (2) Tropical regions have less seasonal variations and have a more or less constant environment. This promotes the niche specialization and thus, high species richness.
Which of the following is a potential reason for the greater number of species in the tropics compared to higher latitudes?
Biodiversity higher in the tropics, but species more likely to arise at higher latitudes. … The results suggest that the latitudinal diversity gradient may be due higher species turnover — speciation counterbalanced by extinction — towards the poles than near the equator.
Which of the following is not the reason of high biodiversity in tropics?
Yaa…the right answer is “Greater environmental variations”…
What is high biodiversity?
High biodiversity is a habitat or ecosystem that has a high number of different species.
What are the 4 types of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
What are the 4 major components of biodiversity?
The four major components of biodiversity are species diversity, ecological diversity, genetic diversity, and functional diversity.
What is the greater 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.
Where is biodiversity the highest?
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 tropical environment able to support greater species diversity give any two reasons?
Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity.
Why is there greater 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.
Why is there greater biodiversity at the equator than at the poles?
Having more energy available in this area means more consumers can be supported. That the are is relatively stable in terms of environment when compared to polar regions has also been suggested as a reason for increased biodiversity at the equator. This stability has meant species are less likely to go extinct.
Why species diversity is highest at the equator?
A new study led by Oxford Earth Sciences’ Associate Professor Erin Saupe suggests that higher species diversity in equatorial regions may be caused by higher rates of speciation (the formation of new and distinct species in the course of evolution), driven by changes in precipitation across space and through time.
