उत्तर
The species-area relationship is represented on a log scale as a linear.
Explanation:
On a log-log scale, the relationship between species richness (S) and area (A) is given by:
log S = log C + Z log A
This is the equation of a straight line (linear relationship), where:
- Log S is plotted on the y-axis
- Log A is plotted on the x-axis
So, on a logarithmic scale, the relationship is linear.
