Red worms have a structure named ______ which helps them in grinding their food.

Gizzard

The correct answer is Option (2) -Gizzard

Red worms have a structure named: Gizzard

The gizzard is a muscular organ found in the digestive tract of certain animals, including red worms (also known as earthworms). In red worms, the gizzard serves as a grinding chamber where ingested food is broken down and pulverized into smaller particles. This grinding action helps in the mechanical digestion of food, preparing it for further digestion and absorption in the intestine. Food is ground up in the gizzard. Sandy particles, or grit, from the soil smash food into tiny pieces by assisting in the breakdown of tough plant material and organic matter consumed by the worms. Once food is sufficiently ground in the gizzard, it passes into the intestine for further digestion and absorption of nutrients.
