Z S C A
d) 1 2 3 4
A C S Z

Options

A. a) `{:(1,2,3,4),(C,S,Z,A):}`
B. b) `{:(1,2,3,4),(S,Z,C,A):}`
C. c) `{:(1,2,3,4),(Z,S,C,A):}`
D. d) `{:(1,2,3,4),(A,C,S,Z):}`

Answer

B

Explanation

The relationship between species richness and area is rectangular hyperbola for a wide variety of taxa whether they are birds, bats, freshwater fishes or flowering plants and the equation can be given as `S=CA^(Z)`. On a logarithmic scale it is straight line described by the equation `logS=logC+Z log A`. Where `S` is species richness, `Z` is slope of line or regression coefficient, `C` is `Y`-intercept while `A` is area.
