Pesticides are generally ineffective in killing coffee berry borers. ecologist daniel karp and colleagues conducted a study in costa rica to determine if natural predators like birds reduce the beetle population. the researchers selected 12 control plots and used nets to exclude birds from 12 similar treatment plots. what is the take-home message of the graph?

There will be more beetles in the plots with no birds

Explanation:

Even though the question excludes the graph needed for an answer, we can still get a general answer.

In the world, habitats can be found where some species are more abundant than others, however adding another animal into that habitat can change the ratio of many species. For example, if there is a habitat with grass and deer, the deer will eat the grass and their population will grow, however introducing a predator into that environment will reduce the population of the deer.

Using the same logic in this question, we can assume that there will definitely be more coffee berry borers in the plots with no birds, because there will be no predators to the beetles' population in check.

really dont know just need some points
