  KEYWORDS: Biological Model, Existence, Periodic Solution, Time Delay, Independent Survival

  ABSTRACT: Based on the classic Lotlk-Volterra cooperation model, we establish a time-delay model of which a species cannot survive independently. By continuation theorem, we discuss existence of positive periodic solutions of the model.
