We study a forager-exploiter model with nonlinear diffusions{ut=((u+1)mu)(uw),vt=((v+1)lv)(vu),wt=Δw(u+v)wμw+r in a smooth bounded domain ΩRn with homogeneous Neumann boundary conditions, where μ>0 and r is a given nonnegative function. We prove that, ifm1andl[1,)(n(n+2)2(n+1),), then the classical solution exists globally and remains bounded.
