Question

Why do earthworms find it difficult to move on grass ?

Answer 1

Answer:

Worms have little microscopic hairs on their bodies that aid them in locomotion. ... The glass may also be dry, in which the worm will lose moisture and end up sticking to the glass then dying because it cannot move anymore. This is why we see worms crossing concrete and gravel after moderate rain.

Answer 2

worms are very thin and flexible.they have two eyes front and back they move both side .they feel difficult to walk on the glass because they have tiny microscopic hairs on their body that aid them in locomotion .the glass is a extremely smooth surface where they crawl in or on the glass ..the glass may be dry and the worms lose the moisture and feel difficult to move
