Why does biodiversity decrease further from the equator?
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.
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.
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 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 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.
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.
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.
