Approximately what percentage of all insect species are of minor importance?

The correct answer is 99%. In the context of insect species, the vast majority are often classified as minor or of little economic or ecological significance. Insects play numerous roles in the ecosystem, but only a small fraction (around 1%) are considered pests or have significant interaction with human activities, such as agriculture or public health. This highlights the abundance of insect diversity while emphasizing that only a tiny subset has a major impact or is regarded as harmful. Understanding this concept is crucial for pest management and ecological conservation, as it influences how we approach pest control methods and appreciate beneficial insects.
