Does biodiversity decrease as you move away from the equator?

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 closer to 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.

What decreases as we move away from the equator?

In any sphere the circumference is lengthier at 0°. So equator is lengthiest latitude and the degree increases or move away from equator to pole the circumference of globe decreases hence latitudinal length also decreases. The length of a parallel increases as we move away from the poles towards the equator.

Why does diversity among species decline as we move away from equator?

species diversity decreases as we move from equator towards the poles because sunlight is less visible due to slanting rays of the sun but at equator posses straight rays of sunlight due to which vegetation of tropical region is much high than the polar regions.

Does biodiversity increase near the equator?

Biodiversity increases towards the equator because the equator has a favorable climate rich in nutrients and sunlight that promotes the development of…

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.

Why is biodiversity greatest near 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.

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.

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 the Temperature decrease as you move from the equator to the North Pole?

Answer: Temperature decreases progressively from equator towards the poles because the sun is less far from the equator and it receives more and direct sunlight and as we go to equator it decreases and in poles it becomes very little or none.

Has we move away from the equator the size of the latitudes?

We see in Figure 2.2 that as we move away from the equator, the size of the parallels of latitude decreases. Besides the equator (0°), the North Pole (90°N) and the South Pole (90° S), there are four important parallels of latitudes– (i) Tropic of Cancer (23½° N) in the Northern Hemisphere.
