Question

as the number of insect species declined due to spraying, the blueberry production decreased. Explain how these two events might be related even though the pesticides did not land directly on the blueberry plants

Answer 1

The  insect  species  and  the   blueberry  relate  through  pollination.  Insects  species  such  as bee  are  agent  of   pollination. pesticide  kills  the  insect  responsible  for  pollinating  flowers  and  thus without  pollination  of  the  flowers  no  blue  berries  are  formed  resulting  to  their  decrease.

Answer 2

the pesticides being sprayed can still land on the blueberry plants if it is windy the day they are spraying the pesticides may not land where they are intended. it can also be carried by bees, butterflies, or other insects from one plant to another.
