What term describes any unwanted organism?

Explanation:
A pest is the term used for any organism that is unwanted because it causes damage, harm, or nuisance. It is a broad category that includes insects, weeds, vertebrates, and even pathogens when they create problems. The other terms don’t fit as well: beneficial refers to organisms that provide value, so they are not unwanted; nuisance describes something annoying but isn’t a formal label for organisms that require management; invader focuses on origin or introduction, not on whether the organism is unwanted or harmful. So the correct term for any unwanted organism is pest.
