Question

what is a risk of using chemical pesticides on crops?
a.
chemical contamination of streams and rivers
b.
attracting more insects to the harvestable product
c.
genetic mutation of existing crops
d.
rotating crop production

Explanation:

Chemical pesticides can leach into water bodies like streams and rivers through runoff, causing contamination. Option B is incorrect because pesticides repel/kill insects, not attract them. Option C is unrelated as pesticides don’t cause genetic mutation in crops directly. Option D is not a risk—rotating crops is a separate farming practice.

Answer:

A. chemical contamination of streams and rivers
