How do contact pesticides work?

  1. By being absorbed by roots or leaves

  2. Through direct contact with the organism

  3. By altering plant or animal growth

  4. By drying plant tissues

The correct answer is: Through direct contact with the organism

Contact pesticides work by directly making contact with the organism, such as insects or weeds, and affecting their nervous system or hormones. Option A is incorrect because contact pesticides do not need to be absorbed by the roots or leaves to be effective. Option C is incorrect because contact pesticides do not alter plant or animal growth but rather directly target the organism causing harm. Option D is incorrect because drying plant tissues is not the main mechanism of action for contact pesticides.
