Q. What is the exact latitudinal range for tropical regions, which harbour more species than temperate or polar areas?
A) $71{^\circ}N\$to $71{^\circ}S$
B) $23.5{^\circ}S\$to$\ 71{^\circ}N$
C) $23.5{^\circ}N\$to$\ 23.5{^\circ}S$
D) $71{^\circ}N\$to$\ 23.5{^\circ}S$
Explanation
In general species diversity decreases as we move away from the equator towards the poles. With very few exceptions, tropics harbour more species than temperate or polar areas. Latitudinal range for tropics is $23.5{^\circ}N$ to $23.5{^\circ}S$
