Final answer:
The lowest taxonomic category shared by both insects and millipedes is the phylum level, known as Arthropoda. Insects are part of the subphylum Hexapoda, while millipedes fall under the subphylum Myriapoda.
Step-by-step explanation:
The lowest taxonomic category shared by both insects and millipedes is the subphylum level. Insects belong to the subphylum Hexapoda, which is characterized by having three pairs of legs and a body divided into three parts: the head, thorax, and abdomen. On the other hand, millipedes are part of the subphylum Myriapoda, which includes species with a varying number of legs, ranging from 10 to 750, and are known for their terrestrial lifestyle in moist environments. Despite their differences, insects and millipedes share a higher level of classification, which is the phylum Arthropoda. This phylum includes animals with jointed legs and a segmented body.
The common taxonomic category shared by insects and millipedes is the phylum level. Insects belong to the subphylum Hexapoda, characterized by three pairs of legs and a segmented body with distinct head, thorax, and abdomen regions. They are highly diverse and form a substantial portion of the arthropod group.
Millipedes, on the other hand, belong to the subphylum Myriapoda, which encompasses various multi-legged arthropods. Millipedes, specifically, are recognized for their numerous legs (ranging from 10 to 750) and a body segmented into many sections, showcasing adaptations for a terrestrial lifestyle in moist environments.
Despite these differences, both insects and millipedes belong to the overarching phylum Arthropoda. Arthropods are characterized by jointed legs and a segmented body, making them a diverse and numerous group within the animal kingdom. The phylum Arthropoda includes a wide array of organisms, such as insects, arachnids, crustaceans, and myriapods.
