In this research, modelling of the leaves with the help of divisor functions are worked on. Given a positive integer k (1 ≤ k ≤ 100), we investigate solutions of the equation σ(n) = σ(n + 2k) with odd square-free integer n. Further, for a positive integer l and odd prime q, there are no results of the equation σ2i(n) = σ2i(q). As an application, we pose the basic structure of the leaves model for real-time virtual ecosystem construction derived from the equation of shifted odd divisor functions. Also, the elliptic, flabellate and five-lobes leaves’s area and the growth process of the leaves were made modelling with the help of divisor functions.
