Concept:Species diversity is highest in regions with warm, wet, and stable climatic conditions.
Explanation:The tropical region lies near the equator, mainly between the Tropic of Cancer (
23.5∘ N) and the Tropic of Capricorn (
23.5∘ S).
It has high rainfall and warm temperatures with little seasonal variation.
These conditions support high primary productivity and many ecological niches.
Therefore, tropical rainforests such as the Amazon and Congo basin have the greatest variety of plants and animals.
Temperate and polar regions have fewer species due to colder temperatures and stronger seasonal changes.
Answer:Maximum species diversity is found in the Tropical region.
