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.
Would you expect to find greater biodiversity near Earth’s poles or near the equator explain?
Would you expect to find greater diversity near Earth’s poles or near the equator? Toward the equator because of latitudinal gradient. … Organisms have been going extinct for all of Earth’s existence.
Why is there greater biodiversity at the equator than at the poles?
Having more energy available in this area means more consumers can be supported. 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. This stability has meant species are less likely to go extinct.
Where would you expect to find greater biodiversity?
Using this classification, aquatic biomes cover an immense area and therefore a very large number of species. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity.
Which environment is most likely to have the greatest levels of biodiversity?
The greatest biodiversity is found in the tropical regions of the world, particularly among tropical rainforests and coral reefs. Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction.
Which type of area would you expect to find along the equator?
An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The Earth is widest at its Equator.
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 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.
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.
Which ecosystem would you expect to find the greatest amount of biomass and biodiversity?
Which ecosystem would you expect to find the greatest amount of biomass and biodiversity? Tropical rainforest.
Which time in Earth’s history features the greatest biodiversity?
The worst was the Permian-Triassic extinction event, 251 million years ago. Vertebrates took 30 million years to recover from this event. The fossil record suggests that the last few million years featured the greatest biodiversity in history.
Would you expect to find great biodiversity in the tundra biome Why or why not read more?
Would you expect to find great biodiversity in the tundra biome? … The rainforest has more biodiversity, because there is more food there, and in the tundra there is not much sunlight and its a very cold environment, therefore vegetation is not plentiful, like in the rainforest.
