Using the infographic, explain why bees are classified as insects within the phylum Arthropoda.

Bees are classified as insects within the phylum Arthropoda for several key reasons:

1. Body Structure: Like all arthropods, bees have a segmented body consisting of three primary parts: the head, thorax, and abdomen. This segmented nature is a defining feature of the Arthropoda phylum.

2. Exoskeleton: Bees possess an exoskeleton made of chitin, which is a characteristic trait of arthropods. The exoskeleton provides support and protection, allowing them to thrive in various environments.

3. Jointed Appendages: Insects, including bees, have jointed legs and antennae. This jointed limb structure is essential for their mobility and interaction with their environment.

4. Three Pairs of Legs: Bees have three pairs of legs, a characteristic feature of insects. This anatomical structure allows them to maneuver efficiently while foraging and flying.

5. Wings: Most adult bees have two pairs of wings, which is typical for many insects. These wings facilitate their ability to fly, mate, and search for food.

6. Metamorphosis: Bees undergo complete metamorphosis, transitioning through the stages of egg, larva, pupa, and adult. This life cycle is common among insects and differentiates them from other arthropods that may not experience such drastic changes.

7. Respiratory System: Bees breathe through a network of tubes called tracheae, another characteristic of insects. This system allows for efficient gas exchange directly with their tissues.

In summary, bees are classified as insects within the phylum Arthropoda due to their segmented body structure, exoskeleton, jointed appendages, three pairs of legs, wings, lifecycle that includes complete metamorphosis, and unique respiratory system. These features collectively fulfill the criteria needed for classification as insects.
