The present paper investigates the magnetohydrodynamic (MHD) bioconvection flow in a porous square cavity filled with oxytactic microorganism. The bioconvection flow and heat transfer in porous media is formulated using Darcy model of Boussinesq approximation. Finite element method based on Galerkin weighted residual scheme is used to solve the governing partial differential equations. The computational numerical results are illustrated in the form of streamlines, isotherms, isoconcentrations of oxygen and microorganisms, average Nusselt number and average Sherwood number. In the present study the effects of key parameters such as bioconvection Rayleigh number (Rb), Rayleigh number (Ra), Peclet number (Pe) magnetic field parameter (M) and Lewis number (Le) are presented and analyzed.
