Bacteria are neither invertebrates nor vertebrates; they are single-celled microorganisms classified as prokaryotes. Unlike invertebrates and vertebrates, which are multicellular organisms with complex structures, bacteria lack a nucleus and other membrane-bound organelles. They can be found in a variety of environments and play essential roles in ecosystems, including nutrient cycling and decomposition.
