Question

The table below gives the population (in thousands) of ten species (A-J) in four areas (I-IV) consisting of the number of habitats given within brackets against each. Study the table and answer the question which follows
Area andSpecies and theirnumber ofpopulation (in habitatsthousands)in the AreaABCDEFGHIJI(11)231.20.526.03.11.19.010.3II(11)10.20.621.53.08.21.111.2III(13)11.30.90.482.41.44.20.88.42.24.1IV(13)3.210.111.14.80.43.30.87.311.32.1
Which area out of I to IV shows maximum species diversity?  (correct answer + 2, wrong answer - 0.50)
  1. II
  2. III
  3. IV
  4. I


Solution

The correct option is C IV
In the given table, the area ‘IV’ has maximum species diversity, as there are 10 species (A-J) reside in 12 habitats, while in area ‘III’, the 10 species reside in 13 habitats, so exhibit less diversity than area ‘IV’.

Area 'I' has only 8 kinds of species with 11 habitats and area 'II' has the least species diversity with only 7 kinds of species with 11 habitats.
