Energy Flow Through an Ecosystem Thermodynamics: the study of energy transformations Law 1: Energy can be transferred and changed but it CANNOT be created nor destroyed. Energy only flows through an ecosystem in one direction, from the sun or inorganic compounds to autotrophs (producers) and then...
Energy is what drives the ecosystem to thrive. While all matter is conserved in an ecosystem, energy flows through an ecosystem, meaning it is not conserved. It's this energy flow that comes from the sun and then from organism to organism that is the bas
