Life in other Dimensions

[Ender W.]

I was wondering one day how life might function in other dimensions. I got to thinking about it, and i read online that life couldn't exist in 2 dimensions because it wouldn't be able to eat ( it digestive system would bisect it). I realized though, that it doesn't necessarily need to remain open all the time. In theory it could take in food, close its mouth, digest it, then create a new opening to eject waste material, similar to vacuoles moving in and out of the cell wall to take in and eject food. anyone have any ideas how life could function if other dimensions?

For that matter, not all 3D terrestrial critters have separate orifices for ingestion and elimination. Some are more of a sack, morphologically.
