A reflex is a natural movement brought on by a particular stimulus.
<h3>What is stimulus?</h3>
A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor. The first element of a homeostatic control system is frequently an internal stimulus.

Earthworms are segmented, tube-shaped worms
belonging to phylum Annelida. These are habituating on healthy soils digesting
live or dead organic matter. The following are benefits of an earthworm to a
soil:
*Earthworms create water way systems, that is, water
can seep quickly into the soil, by digging burrows vertically.
*Earthworms forms lasting burrows or mingling the
soil with organic matter to make the soil more porous, thus, more oxygen to
help the plants’ roots.
*Earthworms reduce the firmness of the soil and
improve the cultivation of land.
*Earthworms consume organic matter as well as mix it
with the soil.
