Observe the given graph representing the species-area relationship proposed by Alexander von Humboldt. Match the labels (A, B, C, D) in List I with their correct descriptions or equations in List II. List I List II A Label A I Area B Label B II Species richness C Label C III S = cA^z D Label D IV S = c + z A Choose the correct answer from the options given below:

Options

  1. AA-I, B-II, C-III, D-IV
  2. BA-II, B-I, C-IV, D-III
  3. CA-II, B-I, C-III, D-IV
  4. DA-I, B-II, C-IV, D-III

Correct answer

C. A-II, B-I, C-III, D-IV

Step-by-step solution

The given graph represents the species-area relationship proposed by Alexander von Humboldt. In this graph: The y-axis (Label A) represents Species richness. The x-axis (Label B) represents Area. The curve (Label C) represents the relationship on a normal scale, which is a rectangular hyperbola given by the equation S = cA^z . The straight line (Label D) represents the relationship on a logarithmic scale, given by the equation S = c + z A . Therefore, the correct matching is: A II (Species richness) B I (Area) C II
