Energy Pyramid

How is the flow of energy through an energy pyramid diagrammed?

• From top to bottom, with the largest amount of energy at the top

• From bottom to top, with the largest amount of energy at the bottom

• In a circular motion, with equal energy at all levels

• Randomly, with no specific direction or order
