The process of decomposition requires living entities as their decomposers. These decompose the degraded complexes in the ecosystem and could be bacteria or fungi. The decomposers attack organic or degraded complexes thus transforming them into simpler forms, thereby initiating the process of degradation. In this process, temperature plays an important role and has a great influence. If the temperature is increased, the process is smoothly carried out and if the temperature is low, the process of decomposition is slow. The colder temperature decreases the rate of decomposition while warmer temperature increases the rate of decomposition. For this process, moisture is required. Hence, the correct option is option A – low temperature, it inhibits the process of decomposition.
