The current communication explore the nonlinear thermal radiation and heat absorption/generation aspects in rate type nanofluid containing gyrotactic microorganism. The bidirectional periodically moving surface induced the flow. The nonlinear radiation features are elaborated in the heat equation. With applications of apposite primarily quantities, the governed equations are transmuted into non-dimensional form. The homotopic procedure is followed to result the simulation analysis. A comprehensive physical analysis is performed for velocity, nanofluid temperature, concentration distribution and motile microorganism profile. The numerical evaluation for change in heat, mass and motile microorganisms is carefully examined with appliance of various graphs and tables. The observations yield out from current contribution reveal that relaxation parameter and Hartmann number declined the both velocity components. The mixed convection constant sufficiently improves the velocity in contrast to buoyancy ratio forces. The surface heating parameter, Brownian constant and bouncy ratio constant improves the nanofluid temperature. An opposing trend in motile microorganism is noted with Peclet constant and bioconvected Lewis number.
