Question

Why Caterpillar need to shed their skin when they grow bigger?

Answer 1

Answer:

Explanation:

Caterpillars have  exo skeleton. The outer layer of the body is a thick layer of chitin which is a kind of sugar. it is a dead matter, it will not grow and as the insect grows, it's outer cover becomes tight. To accommodate the increase in size, the insect makes a bigger layer of chitin underneath and when this is done, they discard the older, smaller one. It is this exoskeleton that gives the strength to the body.
