What is an undesirable organism that injures humans, desirable plants and animals, manufactured products, or natural substances?

  1. An undesirable substance

  2. A beneficial organism

  3. A vital ecosystem component

  4. A pest

The correct answer is: A pest

An undesirable substance would be a material or chemical that is harmful to humans or other living beings, whereas D specifically refers to an organism that causes physical or economic harm. A beneficial organism would have a helpful impact on its surroundings, so that option is incorrect. A vital ecosystem component would be an essential part of a natural system, rather than a harmful factor. C is also incorrect.
