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.
What is the effect on biodiversity when we move from pole to equator *?
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 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.
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.
What is biodiversity question answer?
What is biodiversity exactly? “Biodiversity” not only refers to the number of individual species, but also the genetic variety within and between species and the diversity of ecosystems and regions. The richness of functions and interdependencies in the relationships of species within ecosystems is also a factor.
How can biodiversity be affected?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
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.
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.
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 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.
What is the effect of species diversity as one moves from high to low altitude?
Biodiversity changes with the changes in altitude. It increases as one moves from higher to lower altitudes. Decrease in temperature and greater seasonal variability are the two major factors responsible for lower diversity at higher altitudes.
Is biodiversity has no effect on change in latitude?
HEY THE ANSWER IS THAT. BIO DIVERSITY IS DECREASE TOWARDS THE EQUATOR.
How ecosystem productivity decrease as we move away from the 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.
