  • Question 1
    1 / -0
    Who observed that within a region, species richness increased with increasing explored area but only upto a limit?
    Solution
    During his pioneering and extensive explorations in the wilderness of South American jungles, the great German naturalist and geographer Alexander von Humboldt observed that within a regional species richness increased with the increasing explored area, but only up to a limit. In fact, the relationship between species richness and area for a wide variety of taxa (angiosperm plants, birds, bats, freshwater fishes) turns out to be a rectangular hyperbola. On a logarithmic scale, the relationship is a straight line described by the equation log S = log C + Z log A where S= Species richness A= Area Z = slope of the line (regression coefficient) C = Y-intercept.
    So, the correct answer is 'Alexander von Humboldt'.
  • Question 2
    1 / -0
    The largest tiger reserve in India is
    Solution
    The largest tiger reserve in India is Nagarjunsagar tiger reserve located in Srisalam. Governed by Project Tiger, administrated by the National Tiger Conservation Authority (NTCA), there are 50 tiger reserves in India. 70 percent of the world's tigers are in India. The Tigers are maintained for their scientific, economic, aesthetic, cultural and ecological values.
    So, the correct answer is 'Nagarjunsagar - Srisalam'.

  • Question 6
    1 / -0
    Which region is rich in species diversity?
    Solution
    • Species diversity increases towards the equator. The two main reasons are phylogenetic niche conservatism and ecological productivity. 
    • The relatively high temperatures in the tropics generate and maintain high diversity. 
    • However, the tropical rainforests in developing countries are getting cleared nowadays, which is leading to a great loss of biodiversity.
    So, the correct answer is 'Tropical region'.
