Observe the graph and select the correct option:
पर्याय
Line A represents, S = CA2
Line B represents, log C = log A + Z log S
Line A represents, S = CAZ
Line B represents, log S = log Z + C log A

उत्तर
Line A represents, S = CAZ
Explanation:
The equation S = CAZ often gives the species-area relationship, where S is the number of species, A is the area, and C and Z are constants. The relationship is typically nonlinear.
