Entomology relates to plant science because insects can be both beneficial and destructive to crops. Which option best describes what entomology studies?

• A. Insects are the sole focus of entomology
• B. Entomology studies soils
• C. Entomology studies weather patterns
• D. Entomology is the study of insects and is part of plant science because insects can be both beneficial and destroy crops

Answer: (D)

Entomology is the study of insects and their roles in ecosystems, including how they interact with crops. In agriculture, insects can be beneficial pollinators and natural enemies of pests, or they can be destructive pests that damage plants. Because crops are central to plant science, understanding insects helps in managing crops and improving yields. The other options miss the core idea: entomology isn’t about soils or weather, and it isn’t solely about insects; it’s about insects and their impact on plants.
