Correct answer: D. Pigeon
- A. Crocodile
- B. Frog
- C. Tiger
- D. Pigeon
Explanation
In the case of a pigeon, the gizzard is the part of their digestive system that helps with crushing and grinding food. Pigeons don't have teeth, so the gizzard, which is a muscular organ, contracts and uses small stones or grit to break down the food they eat. This process helps them extract as many nutrients as possible from their food. So, the gizzard in a pigeon is like a natural food processor.
