  In this paper, we describe the induction functor from the category of native
Mackey functors to the category of biset functors for a finite group $G$ over
an algebraically closed field $k$ of characteristic zero. We prove two
applications of this description. As the first application, we exhibit that any
projective biset functor over $k$ is induced from a (rational) virtual native
Mackey functor. The second application is the explicit description of the
projective indecomposable biset functors parameterized by simple groups.
