On a logarithmic scale, the species area relationship is a straight line described by the equation log S = log C + Z log A. What does S, C, Z and A represent in the given equation? Select the correct answer from the codes given below. {:("Species richness" ,=,1),("Slope of the line",= ,2),("Y-intercept",=,3),("Area",=,4):}

The following graph shows the species area relationship. Answers the Questions as directed. (a) Name the naturalist who studied the kind of relationship shown in the graph. Write the observations made by him.
