The paper discusses the specificity of the approach of ecological biophysics to the study of ecological systems and the Earth's biosphere in general. The problems typical for this section of biophysics and possible approaches to their overcoming are considered. In particular, the problem of the uniqueness of ecological systems can be significantly weakened if it is possible to develop a theory of ecological similarity. The problem of the multidirectional dependence of the stability of real ecosystems and their models on the number of incoming species can be removed by switching to the models of the so-called flexible metabolism. The immense complexity of the biosphere prompts one to turn to conceptual models based on the principle of the worst-case scenario, which allow, at least in general terms, to assess the action and possible contribution of certain mechanisms to global dynamics.
