Why is biodiversity high 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.
How does the tropics show the greatest level of biodiversity?
(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.
How is biodiversity unique in the tropics?
The number of species increases drastically from the poles to the equator. … Scientists estimate that tropical forests contain more than half the species on earth, from plants and insects to birds, amphibians, and mammals. These biologically rich areas are known as biodiversity hotspots.
What is tropical biodiversity?
Biodiversity is defined as the variety of all forms of life, from genes to species, through to the broad scale of ecosystems. … The tropics represent a remarkable biodiversity, including plants, birds, insects like especially ants, beetles, butterflies and termites; amphibians, mammals, and other organism groups.
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.
Why do tropics have greater biological diversity class 12?
The vast tropical region receives the greatest amount of solar energy than any other region. So, the energy input is higher in these regions which leads to greater biodiversity and species variation.
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.
Which of the following is not the reason of high biodiversity in tropics?
Yaa…the right answer is “Greater environmental variations“…
How does biodiversity explain how high biodiversity makes an ecosystem stronger?
Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the “diversity–stability hypothesis.” An ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.
What happens when there is high biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Why species diversity is highest at the equator compared to higher latitudes?
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.
Why is more biodiversity found in tropical region than in temperate region?
“There is greater biodiversity in tropical/subtropical regions than in temperate region. … So, tropics has a longer evolutionary time for species diversification. The temperate enviroment are more seasonal, less constant and unpredictable, therefore less niche specialisation and lesser species diversity are observed.
