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 is biodiversity so high 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.

Why is diversity higher in 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 are there more species in tropical areas than in places farther from the equator?

It is generally seen that there is more biodiversity in the tropical region than the temperate region because of a variety of factors: … The tropical forest has a stable ecosystem as well as a suitable climatic condition and favorable reproductive environment for animal and species to thrive.

How does biodiversity generally changed with increasing distance to the equator?

Generally speaking, diversity increases as you move away from the polar regions and towards the equator. A possible explanation for this is that greater primary productivity at the equator has lead to greater biodiversity. Having more energy available in this area means more consumers can be supported.

Does biodiversity tend to increase or decrease near 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.

Why some areas have higher biodiversity?

Unique Climates and Conditions

One of the most significant and naturally occurring causes of differences in biodiversity across the world is differences in climate. … On the other extreme, moist, tropical zones like the Amazon rainforest support some of the highest levels of biodiversity in the world.

Why is biodiversity so high in the tropical rainforest?

Explanation: The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.

Why is more biodiversity found in tropical regions than in temperate region?

“There is greater biodiversity in tropical/subtropical regions than in temperate region. … The tropical/subtropical region exhibit maximum biological diversity because these region remain undisturbed due to less variable climatic conditions. So, tropics has a longer evolutionary time for species diversification.

Why do warmer climates have greater biodiversity?

Sample Response: Warm climates allow for a year-round growing season. Plants are more available as a food resource, which can support more organisms. … Warm climates allow for a year-round growing season. More availability of plants provides more food resources for a greater number of organisms.

Why do some habitats support higher biodiversity than others?

There are at least three possible scenarios or “routes” that a region may follow to become a biodiversity hotspot: a region can have lots of species because it generates species at faster rates than nearby areas, or because they import species from their surroundings at faster rates (that is, they attract species), or …

What is diversity and biodiversity?

The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

What does biodiversity generally increase from?

Generally, there is an increase in biodiversity from the poles to the tropics. Thus localities at lower latitudes have more species than localities at higher latitudes. This is often referred to as the latitudinal gradient in species diversity.
