Question

Animals possessing a cuticle-based skeleton must undergo moulting (ecdysis) because chitin is:
Options
A Biodegradable and dissolves with growth
B A living tissue that reshapes continuously
C A non-living substance that cannot grow with the animal
Correct Answer
D Too rigid to allow expansion without shedding
Correct Answer

Option C is the correct answer.

Detailed Explanation

Chitin is a non-living substance, so animals with this type of skeletal structure must undergo moulting (ecdysis) to grow. The rigid exoskeleton cannot expand, so it must be periodically shed and replaced with a larger one.

Hint

This non-living material cannot expand, requiring periodic shedding for growth.
