The graph given alongside shows the species area relationship. Study the graph and answer the question:

Identify the situation when Z values are in the range of 0.6 to 1.2.

Explanation

Ecologists have discovered that the value of Z lies in the range of 0.1 to 0.2, regardless of the taxonomic group or the region (whether it is the plants in Britain, birds in California or molluscs in New York state, the slopes of the regression line are amazingly similar). But, if we analyse the species-area relationships among very large areas like the entire continents, the slope of the line to be much steeper (Z values in the range of 0.6 to 1.2).
