Solution:

According to geographer Alexander von Humboldt, with increased area species richness also increases. According to him, a rectangular hyperbola represents the relation between species richness and area for a wide variety of taxa. He observed that within a region species richness increased with increasing explored area but only up to a limit. But on a logarithmic scale, a straight line represents this relationship described by the equation log S = log C + Z log A. S = Species richness A= Area Z = slope of the line (regression coefficient) C = Y-intercept.
