What is brood parasitism? Explain with the help of an example.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Brood Parasitism**:
Brood parasitism is a form of parasitism where one organism (the brood parasite) lays its eggs in the nest of another organism (the host). The host then unknowingly raises the offspring of the brood parasite as if they were their own.

2. **Mechanism of Brood Parasitism**:
