Question

What is the relation between species richness and area?

• A. Species richness is directly proportional to area
• B. Species richness increases exponentially with increase in explored area
• C. Species richness is inversely proportional to explored area
• D. log S = log C + Z log A

Answer 1

Answer: (A), (B), (D)

The correct options are
A Species richness is directly proportional to area
B Species richness increases exponentially with increase in explored area
D log S = log C + Z log A

Species richness is directly proportional to area and increases exponentially with increase in area. $S=C{A}^z$. Here S is species richness, A is explored area, C and Z are constants. By taking log on both sides, we get the equation log S = log C + Z log A
