In this paper we present a comparative study of nine photosynthetic pathways bymeans of their thermodynamic performance. The comparison is made by using the thermalefficiency of light-to-chemical energy conversion and the so-called ecological criterionarising from finite-time thermodynamics. The application of both criteria leads tophotosynthesis made by metaphytes and non sulfur purple bacteria as those of bestthermodynamic performance. In spite of the simplicity of our thermodynamic approachsome insights over the low overall efficiency of photosynthesis is suggested.
