The function of the gizzard in a grasshopper is to grind food. Gizzards are also found in chicken, fish, and some reptiles.
Holding place for food before it enters the gizzard.
It is a temporary food storage chamber.
The function of the crop in an grasshopper is to store the food.
Mammals have the stomach that performs a similar function to the gizzard. The stomach in mammals contracts and grinds food with the help of stomach acids and muscular movements to break down food particles for digestion.
The crop and the gizzard are suitable for holding and processing food. They are built like sacs that are muscular and can crush food into small pieces.
The crop is a muscular pouch in the digestive system of birds that stores and moistens food before digestion, while the gizzard is a muscular organ that grinds and breaks down food using grit or small stones ingested by the bird. The crop is responsible for storage and initial breakdown of food, while the gizzard's main function is mechanical digestion to further break down tough food particles.
The gizzard in a chicken is equivalent to the human stomach. Both organs are responsible for grinding and breaking down food particles to aid in digestion.
