Assrtion : The rate of decomposition of detritus is reduced in the regions of high altitude. It happens due to immobilisation of nutrientsA.

Answer» Correct Answer - C At high altitude, the temperature becomes very low `(lt 10^(@)C)`. It greatly reduces the activity of microbes, principal decomposers. Nutrients immobilisation means tiding up of nutrients material with the biomass of microbes. This immobilisation prevents the nutrients from being washed out from the ecosystem. |
