What happens when gizzard is removed in cockroach?

When the gizzard is removed from a cockroach, its ability to grind and process food is compromised. The gizzard plays a crucial role in the digestion of food by mechanically breaking it down, which is essential for nutrient absorption. Without it, the cockroach may struggle to digest food properly, leading to malnutrition and decreased survival. Overall, the removal of the gizzard significantly impacts the cockroach's digestive efficiency.
