Best answer: Why are there so many biodiversity hotspots 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 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.

Where are the biodiversity hotspots in the tropics?

Biological hot-spots include the Western Amazon (Colombia, Ecuador, Peru), Madagascar, North and eastern Borneo, Northeastern Australia, West Africa, and the Brazilian Atlantic forrest. All of these areas have high diversity and many are threatened by human activities.

Why tropical rainforest has maximum biodiversity?

Both the plant and animal biodiversity produce a wide array of food as well as fabrics. Complete Answer: Option A: The maximum biodiversity is found in tropical rain forests as they are less seasonal, they are neither too hot nor too cold and are more predictable. Therefore, this is the correct option.

Why is there so much diversity 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.

What do all of the biodiversity hotspots have in common?

To qualify as a biodiversity hotspot, a region must meet two strict criteria: It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable.

How many hotspots are there in India?

India has four biodiversity hotspots, i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.

Why is Manipur called a biodiversity hotspot?

Imphal, August 31 2013 : Manipur is home to many plants, animals and microbial resources. … He added that the region is a site for gene diversity of many domestic crops and a secondary site place for several economically important plant and animal species.

Why is it important to identify biodiversity hotspots quizlet?

Biodiversity hotspots are important because it is within these unique ecosystems that many rare and endangered species exist. Therefore, it is important to study and protect these areas.

Why is the biodiversity of a tropical rainforest very high quizlet?

Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.

Why do tropics have greater biological diversity class 12?

The vast tropical region receives the greatest amount of solar energy than any other region. So, the energy input is higher in these regions which leads to greater biodiversity and species variation.

Why is there more biodiversity 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.
