What are parasites?

  1. Organisms that grow, feed, and shelter on or in a host

  2. Organisms that reproduce asexually

  3. Single-celled organisms

  4. Viruses that live in the soil

The correct answer is: Organisms that grow, feed, and shelter on or in a host

Parasites are organisms that grow, feed, and shelter on or in a host. This definition accurately describes what parasites are. They rely on other living organisms for their nourishment and can cause harm to the host. The other options are not accurate descriptions of parasites. Reproducing asexually, being single-celled organisms, or being viruses that live in the soil do not define parasites accurately.
