What are 3 ways can the flow of energy be represented in an ecosystem?

The flow of energy in an ecosystem can be represented through food chains, which illustrate the linear pathway of energy transfer from producers to consumers. Food webs provide a more complex view, showing the interconnected relationships and energy flow among multiple organisms. Additionally, energy pyramids visually depict the decreasing energy availability at each trophic level, highlighting the inefficiencies in energy transfer as it moves from producers to higher trophic levels.
