Why are tropical countries rich in biodiversity?

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

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 tropical regions are rich in biodiversity than temperate regions?

(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 are tropical areas richer in biological resources than polar areas?

One idea is that tropical regions harbor greater biodiversity because they are especially fertile grounds for the formation of new species — i.e., “cradles of diversity.” Another idea is that biodiversity hotspots are less likely to lose the species they already have.

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.

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.

Why is biodiversity so high in tropical rainforests 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.
