an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.
As the arthropod grows up, the exoskeleton sheds in order for the arthropod to grow inside of it.
Because of the hardness and inflexibility of the arthropod exoskeleton, they are not suited to expansion and need to be shed or discarded entirely to allow the arthropod to grow. This action is usually called moulting.
Through shedding their exoskeleton.
An insect does this to grow. It expands rapidly before the next exoskeleton hardens.
Ecdysis is when an arthropod molts its exoskeleton. Molting is necessary. The arthropod exoskeleton is inflexible, so, for it to grow larger, arthropods must molt.
The shedding process of a lobster is called molting. During molting, the lobster sheds its hard exoskeleton in order to grow a new, larger one. This process allows lobsters to grow and regenerate damaged parts of their exoskeleton.
Arthropods grow bigger by shedding their exoskeleton in a process called molting. After molting, the arthropod secretes a new, larger exoskeleton, which allows it to grow until the next molting cycle. This process continues throughout their lifespan, enabling them to increase in size.
This is how they grow. The old exoskeleton splits, then the body expands rapidly before the new exoskeleton hardens.
An animal (insect) with an exoskeleton still grows under its exoskeleton like any other animal (insect). The exoskeleton is like a suit of armor, when the animal (insect) grows to big to fit inside its exoskeleton it sheds it, and a newer exoskeleton will grow to fit the animal (insect).
Arthropods molt (moult) in a process called ecdysis. It is necessary for growth because of the inflexibility of the exoskeleton. The old shell remnants are called exuviae. Note that the term 'anthropod' should not be confused with 'arthropod'; anthropods are humans or humanoids and do not moult in the canonic sense.
If a mealworm turns white, it is likely in the process of molting. Molting is when the mealworm sheds its exoskeleton to grow larger. After molting, the mealworm's new exoskeleton will harden, and it will return to its normal color.
Because of the composition of the exoskeleton. It must of necessity be tough to serve its function. Since it is inflexible, the organism has to periodically shed it (moult) in order to grow; a process called ecdysis.
