“Species diversity decreases as we move away from the equator towards the poles. … This results in decrease in biodiversity towards the poles.
Does biodiversity increase as you move toward 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 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.
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.
What increases or decreases biodiversity?
Biodiversity change is caused by a range of drivers. A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. … Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.
Does biodiversity decreases 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.
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 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.
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.
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.
Why does diversity among species decline as we move away from the 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.
Why the length of the parallel decreases as we move away from the equator towards the pole?
The length of latitude slowly decreases towards the poles due to the rotation of the earth because as the earth rotates a centrifugal force is generated which causes change in its shape that makes it oblate spheroid.
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.
