Name the association in which a parasite is again parasitised.

Explanation

**Step-by-Step Solution:**

1. **Understanding Parasitism**: Parasitism is a relationship between two organisms where one organism (the parasite) benefits at the expense of the other (the host). The parasite relies on the host for food, nutrition, and sometimes shelter.
