– 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 rich in tropical islands?
Islands are often considered biodiversity hotspots due to the variety of species that have evolved to thrive on these remote pieces of land. … The features of island living have led to a high number of endemic species, meaning these species are found nowhere else in the world.
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.
What are 2 reasons that tropical ecosystems have greater biodiversity than temperature ecosystems?
Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such, constant environments promote niche specialisation and lead to a greater species diversity. 2. There is more solar energy available in the tropics.
Why is biodiversity so great around the tropics equator?
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 is biodiversity important in tropical rainforests?
Why is biodiversity so high in the tropical rainforest? There are a number of reasons for biodiversity in the tropical rainforest including: the hot and wet climate provides ideal conditions for many species of plants and animals to thrive. … large areas of rainforest are untouched by humans, allowing nature to thrive.
Why does tropical rainforest have biodiversity?
Although tropical rain forests contain the highest diversity of species measured in terrestrial ecosystems, life-form diversity is higher in dry forest probably because of habitat heterogeneity. Woody plants in tropical rain forest tend to converge to a small number of lifeforms.
What is tropical biodiversity?
It is estimated that tropical forests contain more than half the species on Earth. The tropics represent a remarkable biodiversity, including plants, birds, insects like especially ants, beetles, butterflies and termites; amphibians, mammals, and other organism groups.
Why are tropical areas richer in biological resources than polar areas?
One idea is that tropical regions harbor greater biodiversity because they are especially fertile grounds for the formation of new species — i.e., “cradles of diversity.” Another idea is that biodiversity hotspots are less likely to lose the species they already have.
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 tropical regions are richer in biodiversity than the temperate regions?
It is generally seen that there is more biodiversity in the tropical region than the temperate region because of a variety of factors: … The tropical forest has a stable ecosystem as well as a suitable climatic condition and favorable reproductive environment for animal and species to thrive.
Why are tropical rain forests more rich in biodiversity as compared to temperate forests?
Ample sunlight, consistently warm temperatures and frequent, abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.
What type of place is rich in biodiversity?
Nepal is rich in term of biodiversity. There are high mountains, high hills and plain land of Terai regions where different species of plants and animals are found. And it is rich in physical diversity also.
Why is biodiversity in an ecosystem so important?
Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
Why is more biodiversity better?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.
