Wyoming Pesticide Applicator Certification Practice Test

What is the term for the struggle invented by pest organisms that injure or harm beings or products?

1. An undesirable organism that injures or harms humans

2. A plant that lives for more than two years

3. The downward movement of water through soil

4. Any substance intended for preventing, destroying, repelling, or mitigating pests

The correct answer is: An undesirable organism that injures or harms humans

Pest organisms can cause significant damage to other living beings and products, and this struggle is often described by the term "pest". This includes insects, rodents, and bacteria that can negatively impact crops, homes, and health. While pest organisms can certainly cause harm to humans, it is important to note that pests can also harm other beings and products, not just humans. Therefore, the term used to describe this struggle encompasses all living beings and products, not just humans. As for the other options, they do not accurately describe the concept of pest organisms and do not directly relate to the question. A "plant that lives for more than two years" and "the downward movement of water through soil" are both unrelated to pest organisms. While "any substance intended for preventing, destroying, repelling, or mitigating pests" may be used to combat pest organisms, it does not accurately describe the struggle invented by these organisms. Therefore, option A is the most accurate and comprehensive answer to the question.
