We aim to determine whether galaxy groups, a site of accelerated galaxy evolution and merging, are conducive for accretion onto supermassive black holes (SMBHs). We propose to observe 25 low-redshift (z~0.055) galaxy groups from the 2dFGRS with Chandra/ACIS-I for 10 ksec each to determine their AGN content (L_X>10^41 erg/s) unhampered by obscuration. We will determine whether external or internal processes are important drivers of SMBH growth by utilizing the full morphological information (e.g., bulge-to-disk ratio, asymmetry, tidal features) of AGN hosts available from the ZENS survey. Furthermore, we can determine how the environment regulates both AGN accretion and star formation in the intermediate potential wells of galaxy groups.
