Recently, the flow of ternary hybrid nanofluid (THNF) incorporating gyrotactic microorganisms inside the inclined microchannel has been examined in this novel study. The effect of magnetic field, Brownian motion and thermophoresis phenomenon are taken into consideration. Transformation of partial differential equations (PDEs) model into ordinary differential equations (ODEs) is carried out by using the group transformation method (GTM). According to the novel findings, the Newtonian (n=2) and Non-Newtonian (n≠2) models are investigated from the resulting system of ODEs. The effect of tare requisite parameters on velocity profile, temperature field, concentration and motile microorganisms is shown by various graphs. The fluid flow and temperature profile have been improved with the rising in the value of power-law index. Furthermore, the ternary hybrid nanofluid has more temperature than the nanofluid. The current results were compared to the researchers' results to verify the accuracy of the applied method. The Nusselt number reaches the percentage of 45.49 % when the Prandtl number ranges from 6 to 10
