Given below are three statements (A-E) each with one or two blanks. Select the option which correctly fills up the blanks.
A. The tropics (between _____I_____) harbour more species than temperate and polar regions.
B. For example, Columbia situated near _____II_____, has about 1400 species of birds, while New York (41°N) has 105 species, Greenland (71°N) has about 56 species and India (in the equator region) has _____III_____ species.
C. The number of species of vascular plants in tropics is about _____IV_____ times more of that of temperate forests.
D. The _____V_____ rain forest in Brazil, South America has the greatest biodiversity on earth.
E. Since the origin of life on earth and evolution, there have been five episodes of mass extinction, but the current rate of extinction (6 mass extinction - due to human activities) is _____VI_____ times faster than them, due to human activities:
(a) I - 0°N to 90°S, II - equator, III - 1200, IV - five, V - Amazonian, VI - 100 - 1000
(b) I - 23.5°N to 23.5°S, II - equator, III - 10000, IV - ten, V - Amazonian, VI - 100 - 1000
(c) I - 23.5°N to 23.5°S, II - equator, III - 1200, IV - ten, V - Amazonian, VI - 100 -1000
(d) I - 23.5°N to 23.5°S, II - equator, III - 1200, IV - ten, V - Amazonian, VI - 100 - 10000
A. The tropics (latitudinal range of 23.5° N to 23.5° S) harbour more species than temperate or polar areas.
B. 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.
C. A forest in a tropical region like Equator has up to 10 times as many species of vascular plants as a forest of equal area in a temperate region like the Midwest of the USA.
D. The largely tropical Amazonian rain forest in South America has the greatest biodiversity on earth.
E. Since the origin and diversification of life on earth there were five episodes of mass extinction of species but the current species extinction rates are estimated to be 100 to 1,000 times faster than in the pre-human times and our activities are responsible for the faster rates.
