How does the tropics show the greatest level of biodiversity?

Why do 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.

Why are tropical countries rich in biodiversity?

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.

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.

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 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.

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.

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 do the tropical biomes are the most diverse biomes on the globe?

Such ample sunlight and moisture are the essential building blocks for tropical rainforests’ diverse flora and fauna. Roughly half of the world’s species can be found here, with an estimated 40 to 100 or more different species of trees present in each hectare.

Where do you find the greatest species diversity in the world?

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.

Which ecosystem has highest biodiversity?

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.

Why are tropics the most diverse areas?

There are more species in the tropics because tropical ecosystems have more niches. However, the number of niches in an ecosystem is determined by the number of species in that ecosystem.
