  In this study, we consider the following extended attraction chemotaxis
system of two species parabolic-parabolic-elliptic type with nonlocal terms
  \[ \begin{cases} u_t=d_1\Delta u-\chi_1\nabla (u\cdot \nabla
w)+u\left(a_0-a_1u-a_2v-a_3\int_{\Omega}u-a_4\int_{\Omega}v\right),\quad x\in
\Omega \quad\cr v_t=d_2\Delta v-\chi_2\nabla (v\cdot \nabla
w)+v\left(b_0-b_1u-b_2v-b_3\int_{\Omega}u-b_4\int_{\Omega}v\right),\quad x\in
\Omega \quad\cr 0=d_3\Delta w+k u+lv-\lambda w,\quad x\in \Omega \quad\cr
  \end{cases} \] under homogeneous Neuman boundary conditions in a bounded
domain $\Omega \subset \mathbb{R}^n(n\ge1)$ with smooth boundary, where
$a_0,b_0,\, \,a_1,$ and $ b_2$ are positive and $a_2,\, a_3, \, a_4, \, b_1,\,
b_3,$ and $b_4$ are real numbers. We first prove the global existence of
non-negative classical solutions for various explicit parameter regions. Next,
under some further explicit conditions on the coefficients $a_i,\,
b_i,d_i,l,k,\lambda$ and on the chemotaxis sensitivities $\chi_i$, we show that
the system has a unique positive constant steady state solution which is
globally asymptotically stable. Finally, we also find some explicit conditions
on the coefficients $a_i,\, b_i,d_i,l,k,\lambda$ and on the chemotaxis
sensitivities $\chi_i$ for which the phenomenon of competitive exclusion occurs
in the sense that as time goes to infinity, one of the species dies out and the
other reaches its carrying capacity . The method of eventual comparison is used
to study the asymptotic behavior.
