Explain, giving three reasons, why tropics show greatest levels of species diversity.
उत्तर
Tropics show the greatest levels of species diversity because
(i) More solar energy is available in tropics which promote higher productivity and increased biodiversity.
(ii) There is no favourable season in tropics. Continued favourable environment has helped tropical organisms to gain more niche specialisation and increased diversity.
(iii) Resource availability is higher in tropics.
