Question

long billed curlews eat many different types of insects, including grasshoppers, as a source of food. it has been shown that pesticide use kills many of these insects. how would you expect an increase in pesticide use to affect to the population of long billed curlews in the same area
1.it would increase
2.it would stay the same
3.it would decrease
4.it would not be affected

Answer 1

3. it would decrease

An increase in pesticide use would likely lead to a decrease in the population of long billed curlews in the same area, as their food source (insects) would be killed off by the pesticides. Without enough food to sustain them, the curlews would struggle to survive and reproduce, ultimately leading to a decline in their population.
