• D. Oxygen and glucose

Answer: (C)

Verified step by step guidance

1. Understand the role of decomposers in ecosystems: Decomposers, such as bacteria and fungi, break down dead organic matter, recycling nutrients back into the ecosystem.
2. Identify the primary products of decomposition: As decomposers break down organic matter, they release carbon dioxide (CO₂) and water (H₂O) as byproducts of cellular respiration.
3. Recognize the chemical process involved: Decomposers use enzymes to break down complex organic molecules into simpler substances, which are then used in cellular respiration to produce energy.
4. Consider the ecological impact: The release of carbon dioxide and water by decomposers contributes to the carbon cycle and helps maintain the balance of nutrients in the ecosystem.
5. Connect to broader biological concepts: The process of decomposition is crucial for nutrient cycling, supporting plant growth and maintaining ecosystem health by returning essential elements to the soil.
