Question

what is one way animals get rid of internal parasites?
animals eat bristly leaves to catch parasites inside their bodies.
animals chew bristly stems to help their stomachs digest parasites.
animals brush against bristly plants to snag parasites on their skin.

Explanation:

The question asks about eliminating internal parasites. The third option targets external skin parasites, so it is incorrect. Bristly leaves eaten by animals can physically trap internal parasites, which are then expelled from the body, making the first option correct. The second option is incorrect because bristly stems do not aid in digesting parasites.

Answer:

A. Animals eat bristly leaves to catch parasites inside their bodies.
