I believe the question is meant to be "What is biotic?". If so, biotic is a term that means of or pertaining to life. For example, biotic factors are those factors which are considered to come from living sources while abiotic factors are factors which come from non-living sources.
It seems that "biotoc" is not a recognized term or concept in a scientific or common context. It may be a typo or a misspelling. If you provide more context or correct the term, I may be able to help you better.
Yes.
