Why Does Biodiversity Increase Towards 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.May 29, 2016

Why does biodiversity increase towards the tropics?

The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.

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.

Does biodiversity increase or decrease as you move away from the equator?

Species diversity decreases as we move away from the equator towards the poles. … This results in decrease in biodiversity towards the poles.

Why do species live near the equator?

Is biodiversity increase towards the equator?

Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.

Does biodiversity increase as you go up a mountain?

Unique Biodiversity

Because mountain habitats can change quickly as elevations increase, they are often home to a greater diversity of plants and animals than nearby lowlands.

How does biodiversity generally changes with increasing distance to the equator?

Generally speaking, diversity increases as you move away from the polar regions and towards the equator. A possible explanation for this is that greater primary productivity at the equator has lead to greater biodiversity. Having more energy available in this area means more consumers can be supported.

What does biodiversity generally increase from?

Generally, there is an increase in biodiversity from the poles to the tropics. Thus localities at lower latitudes have more species than localities at higher latitudes. This is often referred to as the latitudinal gradient in species diversity.

What are three benefits of biodiversity?

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. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.

How does biodiversity vary as we go from the equator to poles?

The Bio-diversity varies form Equator and poles.

The species density decreases as we go from equator to poles. This is due to sunshine, vertical habitat, temperature etc that is varied across the regions due to differential sun rays. Rain forest that is rich in bio diversity is near the equator.

Why species diversity increases as you move geographically from the polar regions to the equator?

Why does species diversity increase as you move geographically from the polar regions to the equator? The warmer climate around the equator provides a greater abundance of resources, more solar energy, and warmer temperatures that allow for longer growing seasons and more ectothermic species.

Why are most of the biodiversity hotspots centered on or around the equator?

The sun shines most directly on the equator and as we move away, the sun’s curvatures causes solar energy hitting the earth to be spread out over increasingly large areas.

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.

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 is the equator hot?

Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. … This means more heat from the sun makes it to the surface of the Earth.

Which best explains biodiversity?

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

How does biodiversity affect the stability of an ecosystem?

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.

What makes up the biodiversity of a reason why does it vary due to climate and altitude?

Why does biodiversity vary due to climate and altitude? Because most plants and animals are finely tuned members of a local ecosystem that depends on the temperatures and moisture of their surrounding. … Desert conditions are harsh and support few species, with lowbiodiversity. Tropical jungles support many species.

Why do mountains matter in biodiversity?

Mountains are arguably Earth’s most striking features. They play a major role in determining global and regional climates, are the source of most rivers, act as cradles, barriers and bridges for species, and are crucial for the survival and sustainability of many human societies.

How does biodiversity change with altitude?

Altitude affects tree biodiversity inversely. High altitudes are less diverse than lower altitudes. Dear Anil Shankhwar , Even the it is not pronounced like herbaceous plants, there are reports of range and/or niche shift in tree species towards higher altitudes as a result of global warming.

Does biodiversity increase with increasing precipitation?

According to the study, plant diversity is expected to increase where it becomes wetter. This is probably because the seeds of the species found there may have a better chance of germinating and becoming established.

Why is there more biological diversity closer to the equator than in Canada give reasons for your answer?

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.

Why does a warm climate support high biodiversity?

Diversity increases with temperature

The warmer it is, the greater the diversity. “The more groups of animals and plants you investigate in parallel, the greater the significance of temperature for explaining biodiversity, whereas the importance of all other variables decreases accordingly.”

Why is biodiversity important to human biodiversity?

Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.

How does biodiversity benefit us?

Biodiversity gives resilience—from the microbes that contribute to the formation of the human biome to the genes that help us adapt to stress in the environment—supports all forms of livelihoods, may help regulate disease, and is necessary for physical, mental, and spiritual health and social well-being.

Why is biodiversity important 5 Reasons?

Biodiversity Protects Us. Biodiversity makes the earth habitable. Biodiverse ecosystems provide nature-based solutions that buffer us from natural disasters such as floods and storms, filter our water and regenerate our soils. … Protecting and restoring natural ecosystems is vital to fighting climate change.

Why does species diversity decrease as latitude increases?

Another climate-related hypothesis is the climate harshness hypothesis, which states the latitudinal diversity gradient may exist simply because fewer species can physiologically tolerate conditions at higher latitudes than at low latitudes because higher latitudes are often colder and drier than tropical latitudes.

What is the importance of biodiversity hotspots?

There would be no human society at all. And as the places on Earth where the most biodiversity is under the most threat, hotspots are critical to human survival. The map of hotspots overlaps extraordinarily well with the map of the natural places that most benefit people.

Why are hotspots seen as being so critical to global biodiversity?

Why are hotspots seen as being so critical to global biodiversity? because an exceptional percentage of earth’s plant and animal species live in these locations. because the plants and animal species that live in these places cannot be found nowhere else in the world. Q.

Why is there so much biodiversity on Earth?

There are several key reasons for high biodiversity in tropical ecosystems. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations, whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation.

What is biodiversity and why is it important for an ecosystem?

Biodiversity is a measure of variation at genetic, species and ecosystem levels. It helps to boost the ecosystem and its productivity where every species have a meaning and a role no matter how small. For example, a large number of plant species mean a great variety of crops.

Why is high biodiversity advantageous over low biodiversity?

The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable. Lower/less biodiversity = less sustainable. High biodiversity in an ecosystem means that there is a great variety of genes and species in that ecosystem.

Why is equator important to the equator?

The Equator represents the great invisible circle around the Earth that is everywhere equidistant from the geographic poles and lies in a plane perpendicular to the Earth’s axis. The Equator divides the Earth into the Northern and Southern hemispheres.
