Summary Introduction

To analyze:

The approximate increase in predators of borers per hectare, if the forest cover is doubled in the graph from 15 to 30 percent.

Introduction:

Borers are predated upon by the birds and other predators. This, in turn, improves the crop production of coffee berries as these are infected by the pests. When the forest cover is increased, it eventually leads to the increased population of birds and other predators of borers. The following graph depicts the relationship between the borer predators per hectare and percentage of forest cover. On the basis of the graph, the increase in the predators per hectare must be calculated.
