Question

This curve gives you the number of species residing in a particular area (1,2,3…..11). If all points in the given curve are joined in order 1-2-3-4-5-6-7----so-on-till—11, for how many sets of three points do we see growth followed by decline?(for eg, for the set 2-3-4, first it rises and then it declines)___

Answer 1

If you visualize the given curve after joining the points as mentioned in the question, we will get the following figure

In this curve, the following sets exhibits the criteria mentioned in the question:

2-3-4, 5-6-7, 7-8-9, 9-10-11

Thus, totally 4 sets.
