Exergy is the component of energy that can develop a maximum work capacity with respect to a reference state in the environment. Its application in the study of ecosystems allows the development of theories, models and approaches based on thermodynamics, thus increasing the prediction and the analysis power of environmental and ecological sciences. This revision introduces a synopsis of the concept of exergy and some applications on ecological and environmental studies.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráBiodiversidadEnergíaEcosistemasArticle
