This paper is an exposition with the sole aim of highlighting the relevance of ecosystem models in the analyses of biodiversity. The structure of ecosystem models enables researchers to design and consequently formulate monitoring programs that will be useful to the conservation of biodiversity. Ecosystem theoretical models discussed in the paper include Lotka and Volterra Predator-Prey Model; Constructal Law; Kleiber’s Law; Metabolic Theory of Ecology; Occupancy-Abundance Relationship; Allometry Scaling; Rapoport’s Rule; Ewin’s Sampling Formula; Thorson’s Rule; Rench’s Rule, Unified Neutral Theory of Biodiversity (UNTB), and Ecosystem Forecasting. Lastly Biodiversity Action Plan as one of the applications of Ecosystem Theoretical models project was explained.
