Arrange the following places in ascending order of the number of bird species found there and choose the correct option.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Greenland → New York → India → Colombia
Species diversity generally decreases as we move away from the equator towards the poles, so the number of bird species follows latitude. Greenland, at 71° N, is farthest from the equator and has the fewest species. New York, at 41° N, comes next. India, with much of its land in the tropical latitudes, has more than 1,200 species. Colombia, near the equator, has the most, nearly 1,400.
So the ascending order is Greenland → New York → India → Colombia.
NCERT Extract:
Patterns of Biodiversity – “… 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° N only 56 species. India, with much of its land area in the tropical latitudes, has more than 1,200 species of birds.”
