Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Species Diversity
Option (1) Genetic Diversity — Incorrect. Genetic diversity is the variety inside one species, such as the many strains of rice and varieties of mango. Counting amphibian species compares species, not the genes of one species.
Option (2) Species Diversity — Correct. Species diversity is diversity at the level of species. The Western Ghats have more kinds of amphibians than the Eastern Ghats, so they have greater species diversity of amphibians.
Option (3) Ecological Diversity — Incorrect. Ecological diversity is diversity at the level of ecosystems. India, with its deserts, rain forests, mangroves, coral reefs, wetlands, estuaries and alpine meadows, has greater ecosystem diversity than a country like Norway.
Option (4) Global Diversity — Incorrect. This is not one of the three levels of biodiversity (genetic, species and ecological) described by Edward Wilson. It would only mean the total biodiversity of the earth.
