Explain the level of biodiversity at genetic, species and ecological levels with the help of one example each.

− Genetic diversity - It refers to the high diversity of a species at the genetic level over its distributional range, e.g. India has more than $\displaystyle 50,000$ genetically different strains of rice / The genetic variation shown by the medicinal plant Rauwolfia vomitoria growing in different Himalayan ranges might be in terms of the potency and concentration of the active chemical (reserpine) that the plant produces / India has about $\displaystyle 1000$ varieties of mango / any other correct example. − Species diversity - Diversity at species level / the number of different species in a given region, e.g. Western Ghats have a greater amphibian species diversity than Eastern Ghats. − Ecological diversity - Diversity at the ecosystem level / presence of different types of ecosystems in a particular area. e.g. India has a number of ecosystems like rain forests, coral reefs, deserts / any other correct example.
