Why is there very rich biodiversity in equatorial region?

Why does the equator have high biodiversity?

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 tropical and equatorial regions are rich in biodiversity?

– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.

Why tropical region is rich in biodiversity than 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 is species richness more concentrated in equatorial regions?

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

What type of place is rich in biodiversity?

Nepal is rich in term of biodiversity. There are high mountains, high hills and plain land of Terai regions where different species of plants and animals are found. And it is rich in physical diversity also.

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 rich in tropical islands?

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

Why is biodiversity so high in tropical rainforests?

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 are most biodiversity hotspots located in the tropics?

Researchers argue that tropical species form faster in harsh species-poor areas but accumulate in climatically moderate areas to form hotspots of species diversity. … This phenomenon, known as the latitudinal gradient of species diversity, has helped define the tropics as home to most of the world’s biodiversity.

Why is there less diversity in temperate region?

What is the reason for this difference? Tropical and temperate areas have seen different rates and timing of habitat loss. The major cause of biodiversity loss in recent times is habitat destruction and degradation. … Temperate areas had already lost over half their broadleaf forests by 1950.

Why wet tropical rainforest is rich in diversity as compared to temperate rainforest?

Ample sunlight, consistently warm temperatures and frequent, abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.
