Which diagram shows how much energy is used in each topic level of a system?

The diagram that shows how much energy is used in each topic level of a system is typically a "energy flow diagram" or a " Sankey diagram." These diagrams visually represent the distribution and consumption of energy across various components or processes within a system, with the width of arrows indicating the magnitude of energy flow. Energy flow diagrams help in identifying energy efficiency and losses at different levels of a system.
