(1) Tropical latitudes receive more solar energy than temperate regions, which leads to high productivity and high species diversity. (2) Tropical regions have less seasonal variations and have a more or less constant environment. This promotes the niche specialization and thus, high species richness.
Why is biodiversity so rich in tropical islands?
Islands are often considered biodiversity hotspots due to the variety of species that have evolved to thrive on these remote pieces of land. … The features of island living have led to a high number of endemic species, meaning these species are found nowhere else in the world.
What are 2 reasons that tropical ecosystems have greater biodiversity than temperature ecosystems?
– 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 the tropical area has the highest biodiversity index?
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 biodiversity so much greater in the tropics than in higher latitudes?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
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 are tropical countries rich in biodiversity Upsc?
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.
Why is there very rich biodiversity in equatorial region?
Having more energy available in this area means more consumers can be supported. That the are is relatively stable in terms of environment when compared to polar regions has also been suggested as a reason for increased biodiversity at the equator. This stability has meant species are less likely to go extinct.
What could be the possible reasons for diversity between tropic and temperate region?
In the answer body analyse the reasons for difference in diversity between tropical and temperate regions. The reasons for the difference are – location aspects, climate aspects, history of evolution of the two regions, Niche specialization etc.
Why do tropical rainforests have high productivity and why do tropical rainforests have high biodiversity?
Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. … Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.
What is tropical biodiversity?
It is estimated that tropical forests contain more than half the species on Earth. The tropics represent a remarkable biodiversity, including plants, birds, insects like especially ants, beetles, butterflies and termites; amphibians, mammals, and other organism groups.
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.
What is the most important reason for decrease in biodiversity?
-The main reason for the decrease in biodiversity is overpopulation, global warming, deforestation, and pollution.
