Grade 5 students follow how matter cycles between living and nonliving parts of an ecosystem. This worksheet uses fill in the blanks and matching to practice carbon dioxide, oxygen, and water cycle ideas, helping Grade 5 learners see how producers, consumers, and decomposers share matter again. Students see how energy moves through producers, consumers, and decomposers in connected food webs across pond, forest, and meadow Grade 5 examples.
Style:
Energy in Ecosystems
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Matter in an ecosystem is constantly being recycled.
2. Plants take in carbon dioxide from the air during photosynthesis.
3. Animals breathe out carbon dioxide that plants then take in.
4. Plants release the gas oxygen during photosynthesis.
5. Water moves through ecosystems in the water cycle.
6. Nutrients return to the soil when decomposers break down dead matter.
7. Plants pull water and nutrients from the soil through their roots.
8. All the living and nonliving parts of an area form an ecosystem.
9. Energy in an ecosystem flows in one direction, but matter cycles.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Carbon dioxide
→ Gas plants take in for photosynthesis
Gas plants take in for photosynthesis
Oxygen
→ Gas plants release that animals breathe
Gas plants release that animals breathe
Water cycle
→ Movement of water through Earth and the air
Movement of water through Earth and the air
Ecosystem
→ All living and nonliving parts of an area
All living and nonliving parts of an area
