Identify ecosystem energy flow
Free printable Biology science worksheet for "Identify ecosystem energy flow" — practice ecology. No-prep, print or assign online.
High school students trace the flow of energy through ecosystems in this Life Science worksheet, examining how producers, consumers, and decomposers transfer energy across trophic levels. Teachers can use it during an ecology unit to consolidate understanding of food webs and trophic efficiency, or as a pre-assessment before quantitative work with the ten percent rule and energy pyramids. The focus on energy flow connects biology to thermodynamics and reinforces the systemic thinking needed for environmental science.
