Question

when fruits or vegetables are imported into the united states from a foreign country, they are always very closely inspected for insects, even though most insects are not really harmful. why is the inspection done?

Explanation:

The inspection is done to prevent the introduction of non - native insect species. Non - native insects can disrupt the local ecosystem. They may have no natural predators in the new environment, leading to over - population. This can damage local plants (including crops), affect other native species that depend on those plants, and cause economic losses (e.g., in agriculture).

Answer:

To prevent the introduction of non - native insect species that could disrupt the local ecosystem.
