AB  - Currently, nanofluid is a hot area of interest for researchers. The nanofluid with bioconvection phenomenon
attracted the researchers owing to its numerous applications in the field of nanotechnology, microbiology, nuclear
science, heat storage devices, biosensors, biotechnology, hydrogen bomb, engine of motors, cancer treatment,
the atomic reactor, cooling of devices, and in many more. This article presents the bioconvection cross-diffusion
effects on the magnetohydrodynamic flow of nanofluids on three different geometries (cone, wedge, and plate)
with mixed convection. The temperature-dependent thermal conductivity, thermal diffusivity, and Arrhenius
activation energy applications are considered on the fluid flow with melting phenomenon. The flow is analyzed
under thermal and solutal Robin’s conditions. The problem is formulated in the mathematical formulation of
partial differential equations (PDEs). The similarity transformations are applied to diminish the governing nonlinear coupled boundary value problems into higher-order non-linear ordinary differential equations (ODEs). The
resulting expressions/equation numerically tackled utilizing the famous bvp4c package by MATLAB for various
interesting parameters. The results were physically and numerically calculated through graphics and tables for
the velocity field, energy distribution, nanoparticles concentration, and microorganisms profile for numerous
parameters. From the obtained results, we discern that the transfer of heat and mass coefficient is high over a plate
and cone in the flow, respectively. The velocity profile is reduced via a larger magnetic parameter. Temperaturedependent thermal conductivity enhances the thermal field. Larger thermophoresis enhanced the concentration
of nanoparticles. The microorganisms’ Biot number boosts the microorganism’s profile.
