**ABSTRACT **

Modeling may be treated as a science concerning with the interaction between mathematics and other subjects – an academic discipline on some aspects of the everyday world .Mathematical models have become important tools in biological investigations and iterative procedures of information collection. . In this paper, brief summary on specific topics of modeling in life sciences is provided for ready reference. Ecology relates to the study of living beings (animals and plants) in relation to their habits and habitats. This discipline of knowledge is a branch of evolutionary biology purported to explain how or to what extent the living beings are regulated in nature. As models in any branch of science and technology, mathematical models in theoretical ecology are of great importance and utility because they both answer and raise questions related to natural phenomena. It is natural that two or more species living in a common habitat interact in different ways with each other. Some possible ecological interactions that exist among species are also illustrated in this paper.
