Answer:
Adamsia - Phylum Cnidaria
Ascaris - Phylum Nematoda
Pila - Phylum Mollusc
Asterias - Phylum Echinodermata
Balanoglossus - Phylum Hemichordata
Explanation:
Adamsia belongs to the phylum Cnidaria belonging to the animal kingdom and comprises the majority of marine animals and freshwater aquatic animals.
Adamsia is the genus of sea anemones that are mutually symbiotic with hermit crabs. Its common name is cloak anemone. In their symbiotic relationship, the anemone gets shelter and the leftover from the hermit crab is the food source for the sea anemone. The sea anemone in turn provides protection to the crab. The hermit crabs transfer the sea anemones to their new shell once it outgrows the old shell.
The phylum Nematoda comprises nematodes and roundworms. It is a broad phylum under the Kingdom Animalia inhabits a broad range of environments. Ascaris belongs to the phylum Nematoda.
Ascaris is a large roundworm, it is an intestinal parasitic worm of humans. They are the common roundworm infection. They infect humans through the faecal-oral route. Ascaris lumbricoides is one of the well-known species.
Pila belongs to the phylum Mollusca. Pila is the second-largest phylum of invertebrate animals. Phylum Mollusc comprises most marine animals.
Pila is the genus of large freshwater snails and aquatic gastropod molluscs having a gill and an operculum. Pila is the common name for gastropods. Pila species serve as the host of a trematode.
Asterias is a genus comprising the Asteriidae family of sea stars. It includes the common starfish, Asterias rubens, etc. All the species have five arms, radial symmetry and are native to shallow ocean regions.
Asterias belong to the Phylum Echinodermata. The members of the phylum include multicellular organisms which are found exclusively in marine water.
Balanoglossus is a genus of acorn marine-burrowing worms found in the oceans. It is usually found in shallow water. They are known to be the evolutionary link between invertebrates and vertebrate animals. They belong to the Phylum Hemichordata. The animals falling under the group are called acorn worms.
They possess a notochord in the upper part of their body. They lack a nerve chord. Hence, Balanoglossus belongs to the phylum Hemichordata.
