Question
The chemical composition of detritus and climatic factors controls the rate of decomposition.
- True
- False
Hint:
Previous studies have determined that the increase of the atmospheric temperature (as long as the humidity remains stable or increases), generates higher decomposition rates so an increase of 1 °C in the atmospheric temperature would also mean an increase in the rate of decomposition of up to 10%.
The correct answer is 'True'.
- Temperature and soil moisture are the most important climatic factors that regulate decomposition through their effects on the activities of soil microbes.
- For example, warm and moist environment favor decomposition whereas low temperature and moisture inhibit decomposition resulting in a build-up of organic materials.
