Why is there more biodiversity near the equator than in Canada?
Why is there more biological diversity closer to the equator than in Canada? … There is a warmer and wetter climate near the equator. There are generally more seasonal rains and the hotter temperature allows for more different kinds of plants to survive.
Where is biodiversity The highest Why?
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 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 does biodiversity tend to be higher in areas closest to the equator or tropical areas quizlet?
Why are areas near the equator have more species richness? Greater amounts of solar energy, heat, and humidity at tropical latitudes lead to more plant growth, making areas nearer the equator more productive and able to support larger numbers of animals.
What kind of climate has a high biodiversity?
Tropical rainforests are the most biodiverse habitats on Earth. They are home to a huge number of different plants, animals, fungi and other organisms.
Why can we find more species near the equator explain at least three factors?
Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change.
Why is the equator so important?
It has to do with some imaginary lines on our planet. These lines are important, because they help people navigate and measure time. The equator is an imaginary line drawn right around Earth’s middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere.
Why does biodiversity decrease towards the poles?
Speciation is generally a function of time and environmental stability, so if conditions are too harsh, it is difficult for the species to survive and adapt. This results in decrease in biodiversity towards the poles. Species diversity decreases as we move away from the equator towards the poles.
What happens when an ecosystem is close to the equator?
Generally, the closer an ecosystem to the equator… Generally, the closer an area is to the equator, the greater the diversity in species. … Tropical ecosystems are more diverse than temperate zone ecosystems because…
Where are the highest levels of biodiversity on our planet?
Tropical ecosystems support higher levels of biodiversity than temperate or boreal ecosystems. Tropical rainforests and coral reefs are the most diverse ecosystems on the planet. Between 50 and 90 percent of Earth’s plant and animal species are found in tropical regions.
What does higher biodiversity mean?
Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.
Which location would likely have the highest biodiversity?
Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
