Which organs shown does an earthworm use for locomotion?
small small legssohail
How earthworms move though they don't have bones?
Bones are not essential for locomotion . Earthworm move by using circular and longitudinal muscles along with setae and shoe accordion like locomotion .
How does an earthworm's circular and longitudinal muscles aid in movement?
Their short bristles or hairs are a great aid to them as well as the peristalsis of their locomotion.
In an earthworm what does the mouth do?
the mouth is used to chew soil and swallow dirt. it actually serves a mean of locomotion for the earthworm
How does an earthworm move without any legs at all?
Earthworm locomotion is conducted by waves of muscular contractions. The contracted segments seize the soil by the claw-like setae. The process of alternating the contracted segment with the relaxed segment causes movement.
The digestive organ in which an earthworm stores food is?
Temporary storage occurs in the crop of an earthworm
Which life function is most directly involved in the control of the muscles of an earthworm that is moving from dry to moist soil?
The life function most directly involved in the control of the muscles of an earthworm moving from dry to moist soil is the nervous system. The earthworm's nervous system, particularly its nerve cord and ganglia, coordinates muscle contractions for movement. Additionally, the sensory receptors in its skin detect moisture levels, enabling the earthworm to respond effectively to its environment. This allows for locomotion toward more favorable conditions.
How does locomotion take place in an earthworm and a snail?
In earthworms, locomotion occurs through a combination of muscular contractions and the use of setae, tiny bristle-like structures that anchor parts of their body to the soil. They move by alternating contraction and relaxation of their circular and longitudinal muscles, allowing them to extend and shorten their bodies. In contrast, snails move using a muscular foot that secretes mucus, which reduces friction and helps them glide over surfaces. Their movement is facilitated by rhythmic contractions of the foot's muscles, allowing them to travel in a smooth, gliding manner.
What is the respiratory organ of earthworms?
The earthworm has no special respiratory organs. Gaseous exchange occurs through moist skin by diifusion.
How do you think the setae on each segment function in locomotion?
Setae on each segment help the earthworm grip the surface it is moving on. By alternately contracting and relaxing its circular and longitudinal muscles, the earthworm can generate the necessary traction to move forward. The setae anchor the body segments to prevent slipping, allowing the earthworm to move effectively through soil or along surfaces.
Can you drowned earthworm?

What would happen to an earthworm if it's setae were removed.?
If an earthworm's setae were removed, it would lose its ability to effectively grip the soil and maintain stability while moving. Setae are tiny bristle-like structures that aid in locomotion by anchoring the worm as it contracts and expands its body. Without setae, the earthworm would struggle to burrow and navigate its environment, making it vulnerable to predation and environmental threats. Ultimately, this could significantly hinder its survival and ability to thrive in its habitat.
