Question

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

• A. Both A and C
• B. Z values lies in the range of 0.6 to 1.2
• C. The slope of the line to be much steeper
• D. Z values lies in the range of 0.1 to 0.2

Answer 1

The correct option is A Both A and C

The value of Z (slope of the line) lies in the range of 0.1 to 0.2, irrespective of the taxonomic group or the region and slopes are similar for smaller areas.

When a very large area like an entire continent is considered, the species diversity increases significantly due to increase in availability of resources.

This results in the value of Z within a range of 0.6 to 1.2 with a much steeper slope.

Hence the correct option is
d. Both A and C
