Answer to Question 1

Nature helps control insect populations in the following ways:

1 . By the presence of mammals, birds, and amphibians that eat insects
2 . By the presence of predatory insects that eat other insects
3 . Through weather, including harsh winters and unusually dry or wet seasons
4 . Through diseases to which insects are susceptible

Answer to Question 2

Parasites can cause blood loss in animals, which can cause fatigue, poor performance, and inefficient development. Parasites can also carry disease from one animal to another.
