    Biodiversity ni aina mbalimbali za aina mbalimbali za maisha zinazopatikana duniani na tofauti ndani ya spishi na ni kipimo cha aina mbalimbali za viumbe vilivyopo katika mazingira tofauti. Hii inaweza kutaja tofauti ya maumbile, tofauti ya mazingira, au tofauti ya aina (idadi ya spishi) ndani ya eneo, biome, au sayari. Viumbe hai duniani huelekea kuwa kubwa zaidi karibu na ikweta, ambayo inaonekana kuwa matokeo ya hali ya hewa ya joto na tija ya juu ya msingi. Katika Kitengo cha 5, utofauti wa maisha huchunguzwa na utafiti wa kina wa viumbe mbalimbali na majadiliano ya mahusiano ya phylogenetic yanayojitokeza. Kitengo hiki kinatembea kutoka kwa virusi hadi viumbe hai kama bakteria, kinazungumzia viumbe vilivyowekwa zamani kama protisti, na kujitolea sura nyingi kwa maisha ya mimea na wanyama.
