How to delete list options after they've been chosen in a survey form

Question

I've created a survey that includes a list of accession numbers (basically social security numbers) of the plants on our grounds. We want to minimize the number of times our photography volunteers send in survey forms of the same plant. To that end, I'd like to know how I can manipulate the survey so that once an accession number is chosen from the list, it disappears as an option to choose. Does anyone know how I could do this?

I'm not sure that that's going to work for me because I'm pulling my list from a feature layer, not an independent spreadsheet.
