What is the function of decomposition in the carbon cycle?

  • A. To produce light energy
  • B. To convert carbon to fuel
  • C. To release carbon dioxide
  • D. To store food for consumers
Correct Answer: C

Rationale: The correct answer is C: 'To release carbon dioxide.' Decomposition in the carbon cycle involves breaking down dead organic matter into simpler substances. During this process, carbon is released in the form of carbon dioxide back into the atmosphere. This release of carbon dioxide is essential for recycling carbon and making it available for use by living organisms. Choices A, B, and D are incorrect because decomposition does not produce light energy, convert carbon to fuel, or store food for consumers; its primary role is to recycle carbon through the release of carbon dioxide.
