Solution

The correct option is A X- Respiration
Y - Photosynthesis
Z-Decomposition
Animals in the living state release carbon dioxide during the respiration and when die decomposers feed on them, degrade them and releases carbon dioxide. This carbon dioxide then absorbed by the plants during photosynthesis for food preparation. Decomposers also feed on dead plants and release carbon dioxide into the atmosphere. Thus, the correct answer is option A.
