Question:

Arrange the following places in ascending order based on the biodiversity of species of birds and choose the correct option.

 

Options:

Colombia → New York → Greenland → India

Greenland → New York → India → Colombia

New York → India → Colombia → Greenland

India → Colombia → Greenland → New York

Correct Answer:

Greenland → New York → India → Colombia

Explanation:

The correct answer is Option (2) - Greenland → New York → India → Colombia

Colombia, India, New York and Greenland have 1400, 1200, 105 and 56 species of birds, respectively. Thus, places with increasing order of biodiversities of species of birds would be

Greenland → New York → India → Colombia

The diversity of plants and animals is not uniform throughout the world but shows a rather uneven

distribution. For many group of animals or plants, there are interesting patterns in diversity, the most well- known being the latitudinal gradient in diversity. In general, species diversity decreases as we move away from the equator towards the poles. With very few exceptions, tropics (latitudinal range of 23.5° N to 23.5° S) harbour more species than temperate or polar areas. Colombia located near the equator has nearly 1,400 species of birds while New York at 41° N has 105 species and Greenland at 71° Nonly 56 species. India, with much of its land area in the tropical latitudes, has more than 1,200 species of birds.
