HORTICULTURE

Detailed explanation-1: -There are more types of arthropods on Earth than of all other animals combined. The major groups of arthropods are arachnids, centipedes, crustaceans, insects, and millipedes. Spiders, mites, ticks, and scorpions are arachnids. These arthropods have only two body segments, eight legs, but no antennae.

Detailed explanation-2: -The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss.

Detailed explanation-3: -Insects are small animals with six legs and a hard outer shell called an exoskeleton. They have their bodies in three parts. Most have wings and antennae.
