उत्तर
- The given equation's graphical representation of the relationship between species and area is as follows:
- The species richness is represented by S in the given equation.
- The regression coefficient Z is the slope of the line. The slope is found to be 1.15 for frugivorous (fruit-eating) birds and mammals in tropical woods on various continents.
