Which term refers to a small arachnid known for being a plant pest and having eight legs as an adult?

• A. Mite
• B. Insect
• C. Mollusk
• D. Disease

Answer: (A)

Eight legs and a plant-pest lifestyle identify the creature as a mite. Mites are arachnids, which means they have eight legs and two body segments and lack antennae. Insects, by contrast, have six legs, three body parts, and usually antennae, so they don’t match this description. Mollusks are a different animal group altogether (snails and slugs) and don’t have eight legs, and a disease is not an organism at all. So the term that fits best is mite.
