Question

Houseflies act as a ___________ source for birds.

• A. Protein
• B. Carbon
• C. Mineral
• D. None of the above

Answer 1

The correct option is A Protein

Houseflies are generally found feeding and breeding on trash and rotten food where they get attached to several pathogens which are further transmitted by these flies to a healthy host. Housefly pupae contain large amounts of protein and are thus especially beneficial to the various birds, reptiles, and insects that prey on them.

So, the correct answer is option A.
