Describe in the detail the species area relationship of biodiversity

Dear Student

Alexander von Humboldt observed that biodiversity increases with increase in explored area. This relationship can be given by,
log S = log C + Z log A

The species area graph is a relationship between area of a habitat and the number of species found there. It is usually constructed for a type of organisms occupying a particular trophic level. 

A wide range of factors determines the slope of this curve including: immigration, extinction, predator prey dynamics , clustering etc.

This curve follows the second law of thermodynamics.

Regardless of the curve shape, the curve follows the following function:

S = cA^z

S- number of species

A - Habitat area

z - Slope of the curve

c - constant which depends on the unit of area used for measurement
