Is biodiversity has no effect on change in latitude?


Does biodiversity increases 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 decrease near 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.

Why is there more biodiversity 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 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 is biodiversity so much greater in the tropics than in higher latitudes?

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

Does biodiversity increase or decrease as we move from the poles to 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 does biodiversity decrease with latitude?

Species density is higher in the tropics (low latitude) than in temperate regions (high latitude) resulting in a latitudinal biodiversity gradient (LBG).

How does biodiversity vary with latitude?

The decrease in diversity when moving from lower latitudes towards higher latitudes is referred to as Latitudinal Diversity Gradient. Generally it is observed that the diversity richness is more in the areas near the equator than at the poles. … Altitude also affects the diversity richness inversely.

What generally happens to biodiversity as the latitude increases?

1600. Species richness in both terrestrial and marine environments generally declines with latitude. … The species richness of terrestrial plants and animals generally increases with elevation.

What latitude is Equator?

The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator.

Which factor affects biodiversity the most?

In freshwater ecosystems:

water regime changes, such as those following the construction of large dams; invasive species, which can lead to species extinction; and pollution, such as high levels of nutrients. More…

Which ecosystem has more biodiversity?

Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

When we move away from Equator the size of the parallels of latitudes?

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. Note: Latitude lines are extensive circles, with the middle at 0° and the pole at 90°.

What happens as we move away from the equator?

Latitude: Temperature range increases with distance from the equator. Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator. This is due to the curved surface of the earth.

Which of the following is not a cause for loss of biodiversity?

Keeping animals in zoological parks is not a cause for loss of biodiversity rather it is a method of conservation of biodiversity.
