Question
Chapter 30, Problem 11TYK
Summary Introduction
To explain: How the exoskeleton of insects help them to be the most successful organism on land, in terms of both species and numbers; and also define the disadvantages to having an exoskeleton.
Introduction: In terms of both the numbers and species, insects are the most successful organism on the earth. More than half of the total diversity found on the planet is of insects. The skeletons found in insects are exoskeleton which covers the outer body of them.
