Detailed explanation-1: -Answer: An earthworm turns away from light. Characteristic referred in this statement is Photophobia.
Detailed explanation-2: -Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from a stimulus of light.
Detailed explanation-3: -Very low intensity elicits movement toward light, positive responses; moderate and high intensities elicit movement away from light, negative responses.
Detailed explanation-4: -They will move away from light because heat from the sun or a light source will dry out their skin and kill them. How do earthworms breathe? Earthworms do not have lungs; instead, they breathe through their skin. Their skin needs to stay moist to allow the passage of dissolved oxygen into their bloodstream.
Detailed explanation-5: -Earthworms respond to a single stimulus with a single, rapid withdrawal of the part stimulated. This is often called the ‘escape response’, reflecting the likely survival value of the reflex. With repeated stimulation, the response diminishes in magnitude and eventually disappears.
