Why are the tropics so biodiverse?

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 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.

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 great around the tropics equator?

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.

Why is a tropical rainforest so diverse?

Rainforests have an abundance of plants and animals for the following reasons: Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. … The abundance of energy supports an abundance of plant and animal species.

Why are tropical rainforests so productive and biodiverse quizlet?

Why are tropical rainforests so productive and biodiverse? -They have abundant light. … Despite its high biodiversity and productivity, this biome contains most of its nutrients in the plants themselves, instead of the soil.

Why is biodiversity so important anyway?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Why is biodiversity so high in tropical rainforests get so low in tundra and desert biomes?

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 is there so little biodiversity in desert biomes?

Both biomes have warm climates, but the desert is very dry, and the rainforest is very wet. The desert has very few organisms, so it has low biodiversity. Some parts of the desert may have no organisms, and therefore zero biodiversity. In contrast, the rainforest has the highest biodiversity of any biome on Earth.

IT IS SURPRISING:  Why is biodiversity necessary and why should it be conserved Brainly?

Why tropical regions are richer in biodiversity than the temperate regions?

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 more biodiversity better?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.

Why are the tropics more diverse than temperate deciduous forests?

Why are the tropics more diverse than temperate deciduous forests? Ample sunlight, consistently warm temperatures and frequent, abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.

What is the biodiversity like in the tropical rainforest?

Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. The Amazon rainforest is the world’s largest tropical rainforest. It is home to around 40,000 plant species, nearly 1,300 bird species, 3,000 types of fish, 427 species of mammals, and 2.5 million different insects.

What defines biodiversity?

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
