• Domain is the highest rank or level in the taxonomy pyramid.
• Kingdom consist of 5 classification. Plantae(plants), Animalia(Animals), Monera(Prokaryote organisms) Fungi(eukaryotic, non-vascular, non-motile and heterotrophic organisms) Protista(eukaryotic organisms that are neither fungi, plant and animal)
• Domain has 3 classification. Archaea are a single-celled prokaryotic organisms. Bacteria are free living prokaryotic organisms. Eucarya is a multicellular organism and has a nucleus.
• Phylum is next to Kingdom.
• Phylum Porifera non-motile organisms with hard outer skeleton. Habitat, in marine.
• Phylum Annelida have segmented cylindrical body bilaterally symmetrical.
• Phylum Anthropoda have jointed legs and bilaterally symmetrical body.
• Phylum Chordata: vertebrates, have a notochord, and have a dorsal nerve cord.
• Animalia can be further classified into phyla such as Porifera (sponges), Cnidaria (jellyfish), Platyhelminthes (flatworms), Nematoda (roundworms), Mollusca (mussels), Arthropods (insects), and Vertebrate (animals with backbones).
