At which latitude is biodiversity the greatest?
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.
Is biodiversity greater in lower latitudes?
Biodiversity is normally greater in the lower latitudes as compared to the higher latitudes. … Along the mountain gradients, biodiversity is normally greater in the lower altitudes as compared to the higher altitudes.
Does biodiversity increase with latitude?
Species density is higher in the tropics (low latitude) than in temperate regions (high latitude) resulting in a latitudinal biodiversity gradient (LBG).
Which of the following has maximum biodiversity?
Option C temperate rainforest: Temperate rainforest is the rainforest found in a temperate climate. They have a high amount of rainfall every year. In the temperate rainforest they have very few species of plants and animals. Option C is incorrect.
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.
Why is biodiversity higher in lower latitudes?
 Low-latitude areas have a greater incidence of solar energy, and often a higher air moisture content than higher-latitude areas. This fuels an elevated primary-productivity, providing more resources to the ecology as a whole, enabling competition, specialization and speciation.
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…
Why is biodiversity higher at 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.
Which zone of the ocean has the greatest biodiversity?
The epipelagic zone stretches from the surface down to 200 m and is home to the greatest biodiversity in the sea, largely because of the availability of sunlight that enables photosynthetic organisms to thrive. Both marine plants and animals are found here.
Which ocean zone has the least biodiversity?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round.
Where is most of the biodiversity found in the ocean?
The ocean contains a wealth of biodiversity, and most of this diversity lives in the sunlit area called the euphotic zone (see Distribution of Life, page 45, for more information).
