Question

The relation between species richness and area is correctly depicted by

• A. log S = log C - Z log A
• B. log S = Z log A
• C. log S = log C + Z log A
• D. log S = log C
• E. log C = log S + Z log A

Answer 1

Answer: (C)

The relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area is described by the species-area curve. It says that log S = log C + Z log A. Here S is the number of species, A is the habitat area, and Z is the slope of the species-area relationship. Larger areas tend to contain larger numbers of species.
So, the correct answer is 'log S = log C + Z log A'.
