Which one the following is false about Habitat loss and fragmentation?
(1) This is the most important cause driving animals and plants to extinction
(2) The most dramatic examples of habitat loss come from temperate rainforests
(3) Once covering more than 14% of the earth
(4) The Amazon rainforest harbouring probably millions of species is being cut and cleared for cultivating soya beans or for conversion to grassland for raising beef cattle

Global species diversity and land area covered by India with respect to world is:

(1) 12%, 7%

(3) 8.1%, 2.4%    

(4) 4%, 3%

The great German naturalist and geographer Alexander von Humboldt observed that within a region species richness increased with increasing explored area, but only up to a limit. In fact, relation between species richness and area for a wide variety of taxa (angiosperm plants, birds, bats, freshwater fishes) turns out to be a rectangular hyperbola. Now find out correct equations shown in the graph:

(a) I - S = CA^Z; II - Log S = log C + Z log A

(b) I - Log S = log C + Z log A; II - S = CA^Z

(c) I - S = CA^Z + log C; II - Log S = log C + Z log A

(d) I - S = CA^Z + log A; II - Log S = log C + Z log A

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.
