Which condition is associated with the fastest decomposition according to Caspar's Law?

Which condition is associated with the fastest decomposition according to Caspar's Law?

• A. Air
• B. Cold air
• C. Earth
• D. Waterlogged soil

Answer: (A)

Decomposition speed is driven by how much oxygen is available for the decomposing microbes. In open air, oxygen is abundant, so aerobic bacteria and fungi can work at high rates and break down organic material quickly. Cold air slows microbial metabolism, so decomposition proceeds more slowly there. Soil or earth has some oxygen, but it’s not as freely available as in open air, so the rate is intermediate. Waterlogged soil traps water in the pores, creating anaerobic conditions that are much less efficient for decay, slowing the process further. Because of these oxygen and temperature effects, decomposition is fastest in air.
