Not all insects are pests; which statement best explains why some insects are not pests?

• A. They always threaten crops
• B. They are never harmful
• C. They do not threaten and can be helpful
• D. They are always pests

Answer: (C)

Not all insects cause problems; many play beneficial roles in ecosystems. A pest is defined by the damage or economic loss it can cause, not simply by being an insect. Some insects do not threaten crops or people and can actually help, such as pollinators and natural enemies that prey on or parasitize pest species. That makes the statement that some insects do not threaten and can be helpful the best explanation. The other options are too absolute and do not reflect the reality that many insects are neutral or beneficial, while only some become pests in certain conditions.
