Please help me with this question.( no links please ). 11. The graph below shows species —area relationship: Area (A) If b denotes the relationship on log scale i)Describe a and b. ii) How is slope represented? Give the normal range of slope. iii) What kind of slope will be observed for frugivorous birds and mammals in a tropical forest? (B) Species diversity of plants (22%) is much less than that of animals (72%). Analyze the reasons for greater diversity of animals as compared to plants.

Dear student,
A) i) The relationship is linear on logarithmic scale ''b'' which is represented by the following equation:-
Log S = Log C + Z log A
where, S = species richness, A = area, C = intercept on Y axis, Z = slope of the line
The equation for graph ''a'' is S = CAz
ii) The value of Z represents slope whose value lies between 0.1 to 0.2
iii) The slope for frugivorous birds and mammals in tropical forest is 1.15
B) The greater diversity of animals as compared to plants can be stated due to the adaptability of animals in changing environments as compared to plants because animals have developed complex nervous system to control their body structure. They could survive in different habitat as compared to plants because they have evolved their body structure and organs according to the needs of the changing environment.
