प्रश्न
What could be the reason for the faster rate of decomposition in the tropics?
उत्तर
The rate of decomposition is regulated by climatic factors like temperature and soil moisture as they have an effect on the activities of soil microbes. The tropics with its hot and humid climatic condition provides an environment which is ideal for the microbes to speed up the process of decomposition.
