What happens to biodiversity as you go further away from the equator?

Explanation: This idea is also referred to as the latitudinal diversity gradient, meaning that as you move from the equator towards the poles, diversity lessens. … Some also believe greater primary productivity at the equator has lead to greater biodiversity.

Does biodiversity decrease near 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.

How does biodiversity change 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.

IMPORTANT:  What is an example of environmental engineering?

Why does biodiversity increase as you get closer to 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.

How ecosystem productivity decrease as we move away from equator?

The intensity of sun light decreases as we move away from the equator towards the poles and hence productivity. 3. In polar regions the temperature is very low so most of the organisms cannot survive in that habitat.

What is the main cause of loss of biodiversity?

Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

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.

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.

How does biodiversity contribute to the sustainability of an ecosystem?

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

Would you expect to find greater biodiversity near Earth’s poles or near the equator explain your answer?

Would you expect to find greater diversity near Earth’s poles or near the equator? Toward the equator because of latitudinal gradient. … Organisms have been going extinct for all of Earth’s existence.

What happens to the level of biodiversity as a habitat gets smaller?

One of the most fundamental theories in biodiversity science describes how the number of species increases as the area of habitat increases; conversely, as habitat is destroyed, species are lost. … There is a potential flaw, however, in how the theory is applied to biodiversity forecasts.

How does the loss of biodiversity affect humans?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

How is biodiversity affected when we move away from the equator towards the poles?

The biodiversity shows a latitudinal and altitudinal gradients. The species diversity decreases as we move away from the equator towards the poles with very few exceptions, tropics harbour more species than temperature or polar areas.

Why does biodiversity decrease towards the poles?

This idea is also referred to as the latitudinal diversity gradient, meaning that as you move from the equator towards the poles, diversity lessens. … 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.

What is the effect on biodiversity when we move from pole to equator Mcq?

Explanation: The latitudinal gradient has the most well-known pattern in diversity having many groups of animals and plants. A decrease in diversity of species is observed while moving from the equator towards the poles.
