Question

Segmentation of Earth Worm is very to:

• A. 10-20
• B. 5-10
• C. 100-150
• D. 150-200

Hint:

The segmented body of an earthworm plays a critical role in its movement, with each segment containing muscles that contract and expand to help propel the worm through soil.

Answer 1

The Correct Option is C

Earthworms belong to the phylum Annelida, which is characterized by a segmented body structure.

Each segment in an earthworm’s body is called a metamer or somite.

The common species like Lumbricus terrestris can have between 100 to 150 body segments.

The segmentation allows for efficient movement and flexibility as the earthworm contracts and expands its muscles to move through soil.

Therefore, the number of segments in an earthworm is usually within the range of 100-150.
