species. This number represents about 90% of the total number of animal species that exist on the earth.

them. This keeps the earth clean. They are also an important part of the diets of other animals. If insects didn’t
exist, there wouldn’t be any plants, the earth would be covered in waste, and many animals would starve to
death. What are some general characteristics of insects?
Q3 What are the basic characteristics of insects?

a hard covering on the outside of their bodies. Their bodies are divided into three sections, and they have six
legs. They also have two antennae, which function like fingertips for touching, noses for smelling and tongues
for tasting.
