Cea mai mare concentrație regăsită într-o cultură este în nucile de Brazilia, cu o cotă de 1%, corespunzând la 10.000 ppm (părți per milion). S-a dovedit că dependente de bariu sunt algele ornamentale (Desmidiaceae), o familie de organisme unicelulare, algele verzi (Chlorophyta) mari de 1 milimetru, care trăiesc în ape dulci, sărace în nutrienți, găsindu-se în special în mlaștini. În celulele lor se găsesc cavități, umplute cu lichide, în care se găsesc minuscule cristale de sulfat de bariu (BaSO<sub>4</sub>). Dacă mai este nevoie de bariu, acesta este extras selectiv din apă (H<sub>2</sub>O) chiar și la concentrații extrem de mici de 1ppb (părți per miliard). Chiar și la ordinele de mărime, concentrațiile mai mari ale calciului, nu schimbă nimic. Invers însă unele organism tolerează și o doză mortală de bariu, de până la 35 ppm (părți per milion). Funcția biologică a cristalelor este încă incertă, se presupune însă a avea un rol în percepția gravitației. S-a dovedit că bariu este esențial pentru plante, deoarece în absența sa, ele încetează să mai crească.
