Final answer:
Moult is a biological process where an animal loses parts of its body (like skin or feathers), which are later regrown. This process allows for growth and renewal of worn-out cells, and adaptation to seasonal changes. It's common in animals like insects, birds, reptiles, and mammals.
Step-by-step explanation:
Moult is a biological process commonly found in certain animals, including insects, birds, reptiles, and mammals. This process is marked by the shedding or loss of bodily parts such as skin, feathers, hair, and exoskeletons, which are typically followed by the regrowth of new ones. The key reason for moulting varies among species but primarily, it allows for growth, renewal of worn-out cells, and seasonal adaptation. For instance, birds often moult their feathers to replace damaged ones or prepare for seasonal changes, whereas snakes shed their skin to allow for growth and remove parasites.
