Question

a farmer decided to use a new pesticide to help eliminate some bugs that were eating his crops.
soon, he notices that there are fewer birds in the area soon.
what is a reason for this?

Explanation:

The birds likely relied on the bugs as their food source. When the pesticide killed the bugs, the birds lost their primary food supply, so they either starved or migrated to find food elsewhere. Additionally, the birds could have been harmed directly by ingesting the pesticide itself or by eating insects that had absorbed the pesticide, leading to a decline in their population.

Answer:

The birds' food source (the bugs) was eliminated by the pesticide, so they either left to find food, starved, or were harmed by consuming the pesticide-contaminated bugs, causing their numbers to decrease.
