Life is that it consumes energy from its environment and can also reproduce itself, need water, membrane, carbon based. Bacteria simple life forms will cells lacking a nucleus (purple, green, cyanobacteria/blue-green), archaea simple, microscopic including methane producers and sulfur oxidizers in deep sea vent, extreme temps/pressures, eukarya complex orgs, multicellular plants, animals, fungi, protoctists(microscopic don"t fit anywhere else) Linnaeus created taxonomy and binomial nomenclature (genus and species), kingdom, phylum, class, order, family, genus, species (most specific) species is the fundamental unit. Plankton include all organisms algae, animals and bacteria that drift with ocean currents, individual form called plankter, can swim, weakly, vertically, make up most of earth"s biomass, 98% species are bottom dwelling, majority of biomass planktonic. Zooplankton are heterotrophic plankton, drifting marine animals, also bacteria, bacterioplankton are very small, viruses also included virioplankton. Holoplankton spend entire lives as plankton, organisms that spend their adults lives as nekton or benthos spend their juvenile stages as metroplankton.
