Question

Explain, giving three reasons, why tropics show the greatest levels of species diversity.

Answer 1

Hint: There are several biodiversity procedures; species richness (the quantity of species in an area) is a single but significant metric that is useful as the common life diversity currency, but in order to completely capture biodiversity, it must be combined with other metrics.

Complete answer:
Biodiversity is the abundance of life on Earth and its variability. Typically, biodiversity is a representation of variation at the level of biology, plants, and habitats. Closer to the equator, which is the outcome of the warm atmosphere and relatively high productivity, terrestrial biodiversity is typically greater. Biodiversity is not uniformly spread on Earth and is highest in tropical areas.

There are three distinct explanations that clarify why the tropics are abundant in biodiversity.
- 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.
- During the ice age, temperate areas were vulnerable to glaciations, whereas tropical regions stayed undisturbed, contributing to a rise in species diversity in the area.

Note: Ecological indicators are scientific frameworks that use quantitative data to quantify facets of biodiversity, environmental conditions, resources or drivers of transition, but do not encompass all dimensions of ecosystems in a specific ecological indicator.
