How does earthworm fix its body parts to the ground with the help of?
Answers
Answer:
earthworms have small hair like structures called setae , they first hold the ground with some setae , they contract their body , they will place their setae again at some other place and contract it again they move by this repeated process..
Earthworms use their muscles to extend their bodies when moving forward. Once they extend, they extend tiny hairlike structures known as setae from inside their bodies down into the soil. These setae act as an anchor so that the worms can then pull the rear part of their bodies forward. Once the back part of the body has been advanced, earthworms retract the setae from the front of their bodies and insert other setae positioned in the rear of their bodies. This allows them to anchor once more, this time pushing their front halves forward again..
