_________ is an example of an invertebrate

Explanation

Invertebrates are animals that lack a backbone or vertebral column. They make up the majority of animal species on earth. The question is asking for an example of an invertebrate. Among the options given, millipede is the correct answer. Millipedes are elongated arthropods with two pairs of legs per body segment. They are detritivores, feeding on decomposing plant matter. Fish, toad, and snake are all vertebrates because they have a backbone. Fish are aquatic vertebrates with gills and fins, while toads are amphibians that can live on land or in water and have a bumpy skin. Snakes are reptiles with a long, slender body and no limbs. Skin is not an animal, but an organ that covers and protects the body of animals. It is important to note that invertebrates constitute a diverse group of animals, including insects, spiders, crustaceans, mollusks, and many more. They play crucial roles in ecosystems as pollinators, decomposers, predators, and prey.
