Identify energy flow
Free printable Biology science worksheet for "Identify energy flow" — practice photosynthesis and respiration. No-prep, print or assign online.
High school Life Science students trace the pathways of energy between photosynthesis and cellular respiration in this worksheet, identifying how energy captured from sunlight is stored and then released to power cellular work. Teachers can use it as a synthesis activity that requires students to connect the two major metabolic pathways rather than treat them in isolation, which deepens conceptual understanding and prepares students for AP-level biochemistry. Energy flow between these processes is also central to understanding the global carbon cycle.
Learning objectives
- Identify how energy flows from photosynthesis into cellular respiration
- Explain how energy is stored and released in the glucose molecule
- Connect energy flow between photosynthesis and respiration to broader ecological processes
