Answer
In India, two examples of exotic species that have caused a reduction in biodiversity are Nilgai and Water hyacinth. Nilgai are large antelope that are native to Africa, but they were introduced to India in the 19th century. Nilgai has since spread throughout much of India, and they have been a major factor in the decline of native grazing animals such as the blackbuck.
