The Eye of Terror is a rift between the Warp and realspace. Supposedly it was the `birth` place of Slaneesh, which caused the borders to thin dangeroulsy, resulting in the Eye. There is a great deal of biomass there, even if it is tainted, and the Eye itself could act as a sorts of gate between the Immaterium and realspace.

We don`t know exactly how the tyranids will react to a massive overexposure to chaos. If the Chaos gods muster and combine their power and create a warp storm in the middle of a Tyranid fleet, it is not known what would happen, or even if it could happen. If over-exposure to Warp energy doesn`t effect the Tyranids significanlty, then they definetly will attack the Eye.
