Assertion : If the species-area relationship are analysed among very large areas like the entire continents, the value of Z, i.e., slope of line in the range of 0.1 to 0.2.
Reason : The value of Z, i.e., slope of line of species area relationship lies in the range of 0.6 to 1.2 when analysis is done among small areas.

The species-area relationships among very large areas like entire continents

For a species - area relationship graph , for which of the values of Z , the slope of line is most steep ?

If the points 1+2i and -1+4i are reflections of each other in the line z(1+i)+bar(z)(1-i)+k=0 then the value of k is

The following graph shows the species area relationship. Answer the following questions as directed. Write the situations as discovered by the ecologists when the value of 'Z' (slope of the line) lies between 0.1 and 0.2 What does 'Z' stand for?
