Compare observations of matter cycling in organisms and describe the pattern you notice
Free printable Grade 7 science worksheet for "Compare observations of matter cycling in organisms and describe the pattern you notice" — practice photosynthesis and respiration. No-prep, print or assign online.
Matter cycling through living organisms — carbon, oxygen, and other elements moving through photosynthesis and cellular respiration — is the focus of this middle school Life Science worksheet, where students compare observations and describe the patterns they notice. Teachers can use it to help students make the conceptual link between the two processes and understand how matter is conserved as it cycles through the biosphere. Recognizing these patterns builds the systems thinking that underlies ecology, climate science, and biogeochemical cycles.
Learning objectives
- Compare how matter cycles through organisms during photosynthesis and respiration
- Identify the pattern in how carbon and oxygen are exchanged between processes
- Explain how matter is conserved as it moves through living systems
