Which of the following is wrong about diversity of birds?
(1) Colombia-1400
(2) New york-105
(3) Greenland-95
(4) India-1200
India has more than 1200 species of birds. This is because
(1) India with much of it's land area in the tropical latitudes
(2) India with much of it's land area in temperate latitudes
(3) India with it's considerable land area in polar latitudes
(4) India with much of it's land area in different altitudes

According to Ecologists and Evolutionary Biologists, the probable reason for speciation in tropics is not
(1) Speciation is generally a function of time, more time without environmental disturbances better chance of speciation
(2) No frequent glaciation unlike temperate regions in the past
(3) Constant environment supports niche specialisation
(4) Tropics had more adapted animals and had a high rate of reproduction so there is more diversity
……a… have remained relatively undisturbed for millions of years and thus had a long evolutionary time for……b..The constant environments promote…c..and had a greater species diversity.
Which of the following is correct?
(1) a-Tropical latitudes
(2) b-niche specialization
(3) c- species diversity
(4) b- constant environment
