Shrimp have 10 legs, termites have 6, and spiders have 8 legs. They all belong to which group of organisms?

The correct answer is that shrimp, termites, and spiders all belong to the group of organisms known as arthropods. Arthropods are characterized by having segmented bodies, an exoskeleton made of chitin, and jointed legs. This diverse group includes insects (like termites), arachnids (like spiders), and crustaceans (like shrimp), among others.

Understanding these classifications is crucial because it highlights the common evolutionary traits shared by these organisms. While the legs count differs—10 for shrimp, 6 for termites, and 8 for spiders—they all fall under the broader category of arthropods, showcasing the diversity and adaptability of this phylum in various environments.

The other answer choices focus on specific sub-groups: Arachnida specifically refers to spiders and their relatives, Myriapoda includes centipedes and millipedes, and Crustacea encompasses various aquatic organisms like crabs and shrimp. However, since the question involves a broader comparison where all specified organisms fit into one large category, arthropods is the most comprehensive and correct choice.
