Frequent question: Why temperate and polar regions have less biodiversity than tropical regions?

Which factor explains that in general, temperate and polar regions have less biodiversity than tropical regions? … The polar regions receive more intense solar energy. The tropical regions contain more micro-ecosystems.

Why is there more biodiversity in tropical regions 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 temperate regions have less biodiversity?

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 is biodiversity more diverse 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.

Which of the following is not considered with loss of biodiversity?

Keeping animals in zoological parks is not a cause for loss of biodiversity rather it is a method of conservation of biodiversity.

Which region has more diversity?

Species diversity is greatest in the tropics, particularly in tropical forests and coral reefs. The Amazon basin in South America has the largest area of tropical forests. The southwestern Pacific has the greatest diver- sity of coral reef species.

Does the temperate rainforest have high or low biodiversity?

The cooler temperatures mean that temperate rainforests are not as biodiverse as tropical rainforests. This means they contain fewer different species of plants and animals. The coniferous temperate rainforests of the U.S. Pacific coast have the highest levels of biomass of any place on earth.

What is the difference between temperate region and tropical region?

The region which has always the temperature 65 degree F or above is a tropical region. Whereas in temperate region, there is variation in temperature but not extreme of cold or hot. … The region lies between the equator and pole.

Why do warmer climates have greater biodiversity?

Diversity increases with temperature

The warmer it is, the greater the diversity. “The more groups of animals and plants you investigate in parallel, the greater the significance of temperature for explaining biodiversity, whereas the importance of all other variables decreases accordingly.”

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.

Where would you expect more species diversity in tropics or in polar regions give reasons in support of your answer?

Tropics have more species biodiversity than that of the polar regions. … ii High productivity : There is more solar energy available in tropics which contributes directly to more productivity population sizes and indirectly to greater species diversity.
