Ecosystems as Self-organizing Holarchic Open Systems
... The first law of thermodynamics arose from efforts, in the early 1800s, to understand the relation between heat and work. The first law states that energy cannot be created or destroyed and that the total energy within a closed system remains unchanged. This laws deals strictly with the quantity of ...
