When an organic compost pile is built correctly (sufficiently large, slightly moist, and containing a variety of organic material), it tends to get hot. Which of the following best explains why a compost pile gets hot?

A: Solar energy hitting the pile causes photosynthetic microorganisms in the pile to begin working and releasing the stored energy as heat.

B: Water molecules within the compost pile spontaneously break down and release their energy as heat.

C:  The decomposers are breaking down energy-containing organic molecules for their own use and some of the energy escapes as heat.
