Which is the outermost non-cellular layer in earthworm's body?
1 Cuticle
2 Epidermis
3 Muscles
4 Clitellum
Explanation:
The body wall of the earthworm is covered externally by a thin non-cellular cuticle below which is the epidermis, two muscle layers (circular and longitudinal) and an innermost coelomic epithelium.

Earthworm can distinguish the light intensities and feel the vibration in the ground through
1 Cuticle
2 Mechanical receptor
3 Receptor cells (touch sensitive organs)
4 Chemoreceptors
Explanation:
Sensory system does not have eyes but does possess light and touch sensitive organs (receptor cells) to distinguish the light intensities and to feel the vibrations in the ground.

The process of increasing fertility of the soil by the earthworms is known as
1 Vermicomposting
2 Worm casting
3 Manuring
4 Green revolution
Explanation:
Earthworms are also known as 'friends of farmers' because they make burrows in the soil and make it porous.This process of increasing the fertility of the soil by using earthworm is called vermicomposting.

Choose the wrong statement regarding earthworm
1 Fertilization is internal
2 It is protandrous
3 Prior to fertilization sperms are exchanged
4 Cocoon is secreted by clitellum
Explanation:
Fertilization is external. Fertilisation and development occur within the cocoons which are deposited in soil. The ova (eggs) are fertilised by the sperm cells within the cocoon which then slips off the worm and is deposited in or on the soil.
